The concepts of mean, mode and median prove to be the fundamentals of probability and statistics. Mean is the average of given numbers, median happens to be the one which is most repeated and likewise the mode has its definition which the candidate must have knowledge of before attending this quiz. The quiz then helps greatly by asking the candidate to solve simple questions related to the topic. They are as simple as like what is the mean of 32,12,19 and the task is to find the mean of these given three numbers. Easy to do but a good practice will help children in many ways.
What is mean, median and mode?
Mean, mode, and median are all ways to describe and analyze sets of numbers. They are often used in math and statistics to make sense of data and to understand patterns and trends.
The mean is the average of a set of numbers. To find the mean, you add up all of the numbers in the set and then divide the total by the number of numbers in the set. For example, the mean of the numbers 2, 4, and 6 is 4, because 2 + 4 + 6 = 12 and 12 / 3 = 4. The mean is a useful way to describe a set of numbers because it gives you an idea of what the typical number in the set is.
The mode is the number that appears most often in a set of numbers. For example, the mode of the numbers 2, 4, 4, and 6 is 4, because 4 appears twice, while the other numbers only appear once. The mode is a useful way to describe a set of numbers when you are interested in the most common number in the set.
The median is the number that is in the middle of a set of numbers when they are listed in order. To find the median, you first need to list the numbers in order from least to greatest. If there is an odd number of numbers in the set, the median is the number in the middle. If there is an even number of numbers in the set, the median is the mean of the two numbers in the middle. For example, the median of the numbers 2, 4, 4, and 6 is 4, because 4 is the number in the middle of the list when the numbers are listed in order from least to greatest (2, 4, 4, 6). The median is a useful way to describe a set of numbers when you want to know the middle value in the set.
Mean, mode, and median can be used together to describe and analyze sets of numbers. For example, if you have a set of numbers that has a high mean, a low mode, and a high median, it might mean that there are a few very high numbers in the set that are pulling up the mean, but most of the numbers are low and that is why the mode is low. On the other hand, if you have a set of numbers that has a low mean, a high mode, and a low median, it might mean that there are a lot of similar numbers in the set that are all pulling down the mean, but there are also a few very low numbers that are pulling down the median.
In conclusion, mean, mode, and median are all useful tools for describing and analyzing sets of numbers. They can help you understand patterns and trends in data and make sense of complex sets of numbers. Whether you are a student or a professional, understanding these concepts can be helpful in many different fields, from science and math to business and finance.

Subtracting Two-Digit Numbers
Subtraction is a mathematical operation that represents the process of taking away a certain quantity from another. In this lesson, we will learn how to subtract one from two-digit numbers.
First, let’s start with an example. Suppose we want to subtract 1 from the number 25. To do this, we start by writing the number 25 on a line and then writing a minus sign (-) followed by the number 1. The equation would look like this:
25 – 1 =
Next, we need to perform the subtraction. Since 1 is smaller than 5, we cannot simply take 1 away from 5. Instead, we need to borrow a ten from the tens place. To do this, we change the 5 in the tens place to a 4 and add 10 to the ones place, turning the 5 into a 15. Our equation now looks like this:
24 – 1 = 15
Now we can perform the subtraction. 15 minus 1 is equal to 14, so our final answer is 14. Let’s write that down:
24 – 1 = 14
Now let’s try another example. Suppose we want to subtract 1 from the number 37. We start by writing the equation:
37 – 1 =
Since 1 is smaller than 7, we need to borrow a ten from the tens place. We change the 3 in the tens place to a 2 and add 10 to the ones place, turning the 7 into a 17. Our equation now looks like this:
27 – 1 = 17
Now we can perform the subtraction. 17 minus 1 is equal to 16, so our final answer is 16. Let’s write that down:
27 – 1 = 16
Great job! You have now learned how to subtract one from two-digit numbers. Remember to always start by writing the equation, then borrow a ten if necessary, and finally perform the subtraction. With practice, you will become an expert at subtracting two-digit numbers in no time!

How to subtract and find missing numbers?
Subtraction is a mathematical operation that represents the process of taking away a certain quantity from another. In this lesson, we will learn how to subtract and find missing numbers.
Let’s start with an example. Suppose we are given the equation 10 – ? = 5. We are trying to find the missing number, represented by the question mark (?). To solve this equation, we need to perform the inverse operation of subtraction, which is addition. We can add 5 to both sides of the equation to find the missing number. The equation becomes:
10 – ? + 5 = 5 + 5
Now we can simplify the equation by performing the addition:
10 – ? = 10
Finally, we can subtract 10 from both sides of the equation to find the missing number:
10 – 10 – ? = 10 – 10
This simplifies to:
-? = 0
The missing number is equal to 0. So, the original equation 10 – ? = 5 has the solution ? = 0.
Now let’s try another example. Suppose we are given the equation 15 – ? = 9. To find the missing number, we can add ? to both sides of the equation:
15 – ? + ? = 9 + ?
This simplifies to:
15 – ? = 9 + ?
Now we can subtract 9 from both sides of the equation:
15 – 9 – ? = 9 – 9 + ?
This simplifies to:
6 – ? = ?
Finally, we can subtract ? from both sides of the equation:
6 – ? – ? = ? – ?
This simplifies to:
6 – 2? = 0
To solve for the missing number, we need to divide both sides of the equation by -2:
(6 – 2?)/-2 = 0/-2
This simplifies to:
-3 – ? = 0
Finally, we can add 3 to both sides of the equation to find the missing number:
-3 + 3 – ? = 0 + 3
This simplifies to:
-? = 3
The missing number is equal to 3. So, the original equation 15 – ? = 9 has the solution ? = 3.
Great job! You have now learned how to subtract and find missing numbers. Remember to always perform the inverse operation of subtraction, which is addition, to find the missing number. With practice, you will become an expert at solving equations in no time!

Arrange the numbers in order
Have you ever had a bunch of numbers and needed to put them in order from the greatest to the least? This is called “ordering numbers” and it’s a really useful skill to have. You can use it to solve math problems, or just to organize a list of numbers.
To put numbers in order from greatest to least, all you have to do is compare the numbers and arrange them from the largest to the smallest. It’s just like putting books on a shelf – you start with the tallest book on the bottom and work your way up to the shortest book on the top.
For example, let’s say you have the numbers 4, 7, 5, and 9 and you want to put them in order from greatest to least. First, you would compare the numbers 4 and 7. 7 is greater than 4, so 7 should go first. Then, you would compare the numbers 5 and 9. 9 is greater than 5, so 9 should go next. Finally, you would compare the numbers 4 and 5. 5 is greater than 4, so 5 should go last.
So, the correct order for the numbers 4, 7, 5, and 9 from greatest to least is: 9, 7, 5, 4.
It’s really important to be careful when you’re ordering numbers. Make sure to compare each number to every other number to make sure you have the right order.
Here’s another example: let’s say you have the numbers 2, 6, 3, and 8 and you want to put them in order from greatest to least. First, you would compare the numbers 2 and 6. 6 is greater than 2, so 6 should go first. Then, you would compare the numbers 3 and 8. 8 is greater than 3, so 8 should go next. Finally, you would compare the numbers 2 and 3. 3 is greater than 2, so 3 should go last.
So, the correct order for the numbers 2, 6, 3, and 8 from greatest to least is: 8, 6, 3, 2.
I hope this explanation of how to put numbers in order from greatest to least was helpful! Remember, all you have to do is compare the numbers and arrange them from the largest to the smallest. Have fun practicing and using this skill!

Teaching symmetry of objects
Have you ever seen a picture or an object that was split down the middle and one half looked exactly like the other? This is called symmetry. Symmetry is when one half of an object is a mirror image of the other half.
There are many different types of symmetry. One type is called “vertical symmetry.” This is when an object is split down the middle and one half is a mirror image of the other half. For example, the letter “H” has vertical symmetry. If you fold it down the middle, both sides look exactly the same.
Another type of symmetry is called “horizontal symmetry.” This is when an object is split in half horizontally and one half is a mirror image of the other half. The letter “I” has horizontal symmetry. If you fold it in half horizontally, both sides look exactly the same.
There are also other types of symmetry, like diagonal symmetry and rotational symmetry. Diagonal symmetry is when an object is split in half by a diagonal line and one half is a mirror image of the other half. Rotational symmetry is when an object looks the same no matter how many times you turn it around.
Symmetry is a really interesting and important concept in math and science. It can help us understand the world around us and make predictions about how things will behave. For example, scientists use symmetry to understand the properties of molecules and atoms.
Symmetry can also be found in art and design. Many artists and designers use symmetry to create beautiful and interesting patterns and compositions.
I hope this explanation of symmetry was helpful! Remember, symmetry is when one half of an object is a mirror image of the other half. There are many different types of symmetry, and it can be found in math, science, art, and design. Have fun looking for symmetry in the world around you!

Writing Numbers As Tens And Ones easy Math quiz
32 FREE Math Ebook Downloads For Members
Place value for kids
Writing numbers as tens and ones is an important skill for children to learn as it helps them to understand place value and the base-ten number system. In this system, the value of a digit depends on its place in the number. For example, in the number 4321, the 4 is in the thousands place, the 3 is in the hundreds place, the 2 is in the tens place, and the 1 is in the ones place.
To write a number as tens and ones, you can separate the digits into two groups: the tens and the ones. For example, the number 23 can be written as 20 tens and 3 ones. This is because 2 tens is equal to 20 and 3 ones is equal to 3. When you add the two groups together, you get 23.
You can also use this technique to write larger numbers. For example, the number 358 can be written as 3 hundreds, 5 tens, and 8 ones. This is because 3 hundreds is equal to 300, 5 tens is equal to 50, and 8 ones is equal to 8. When you add these three groups together, you get 358.
Writing numbers as tens and ones can also help you to round numbers to the nearest ten or hundred. For example, if you have the number 37, you can round it to the nearest ten by looking at the ones place. Since the number in the ones place is 7, which is greater than 5, you would round up to the nearest ten, which is 40. If you had the number 149, you could round it to the nearest hundred by looking at the tens and ones place. Since the number in the tens place is 4 and the number in the ones place is 9, which are both greater than 5, you would round up to the nearest hundred, which is 200.
Writing numbers as tens and ones is also useful when you are adding and subtracting numbers. For example, if you wanted to add the numbers 26 and 17, you could first write them as 20 tens and 6 ones and 10 tens and 7 ones. Then, you could add the tens and the ones separately to get 30 tens and 13 ones, which is equal to 43.
In conclusion, writing numbers as tens and ones is a valuable skill that helps children to understand place value and the base-ten number system. It can also be used to round numbers, add and subtract numbers, and understand larger numbers. With practice, children can become proficient at writing numbers as tens and ones and use this skill in their everyday lives.
