Basic arithmetic operations when they are done individually it is easy to solve the problems.But it becomes confusing when in a single expression result has to evaluated and that expression has a combination of arithmetic operations. For example, in an expression such as 3+4-2×5/(2-1) it is quite tricky because, without the knowledge of the order of operations, it is tough to select from where the expression has to start simplifying. To resolve this issue, BODMAS technique is the norm that should be followed and here this quiz makes the child to be habituated in using this principle.

Learning to solve equation using BODMAS / PEMDAS

The order of operations is a set of rules that tells us the correct order to solve math problems. It helps us to make sure that we get the right answer every time.

The order of operations can be remembered with the acronym PEMDAS:

P: Parentheses first. Anything inside parentheses should be solved first.

E: Exponents (ie Powers and Square Roots, etc.)

MD: Multiplication and Division (left-to-right)

AS: Addition and Subtraction (left-to-right)

Here’s an example:

Say you have the math problem: 3 + 4 x 5

Using the order of operations, we first solve the part inside the parentheses. There are no parentheses in this problem, so we move on. Next, we look for exponents. There are none, so we move on. Now we look for multiplication and division, and we find that 4 x 5 is 20. We solve this part first and get:

3 + 20 = 23

Finally, we add 3 + 20 to get our answer: 23.

If we had not followed the order of operations, we might have gotten a different answer. For example, if we had added 3 + 4 first and then multiplied the result by 5, we would have gotten 35, which is not the correct answer.

It’s important to follow the order of operations carefully to make sure that we get the right answer every time.

Examples:

  1. 6 + 3 x 4 = 18
  2. (6 + 3) x 4 = 24
  3. 8 – 4 + 6 x 3 = 14
  4. 8 – (4 + 6) x 3 = -10
  5. 2 + 3 x 4 ÷ 6 = 2
  6. 2 + (3 x 4) ÷ 6 = 3
  7. 8 – 4 x 3 + 2 = 2
  8. 8 – (4 x 3) + 2 = -2

Remember, the order of operations is important because it helps us to solve math problems correctly. Always start with the part inside the parentheses, then exponents, then multiplication and division (from left to right), and finally addition and subtraction (from left to right). By following these rules, you’ll be able to solve math problems confidently and correctly.
