This is ideally a good exercise for the children to work more on the concepts of subtraction because, in this quiz, it involves just subtracting a single digit number from the given two-digit numbers. Though it looks very basic, yet indeed is a classical way of helping the child to pick up the essence of subtraction as the quiz doesn’t involve any complicated subtractions, rather simple ones. In this quiz, there is one more concept that creeps in, the borrowing, which is a bounty while practicing. The more the child practices the questions in this quiz, more comfortable will the child feel about the concepts of borrowing and subtraction.

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!
