# 5th Class (CBSE) Mathematics: Order Of Operations

#### A. When you have an expression with different operations follow this order:

Division  Multiplication  Addition  Subtraction

You can remember this order as DMAS.

Following the rules.

Let us look at some examples.

a) 53 – 18 ÷ 2 x 5

= 53 – 18 ÷ 2 x 5      First divide

= 53 – 9 x 5               Next, multiply

= 53 – 45 = 8            Finally, subtract

53 – 18 ÷ 2 x 5 = 8

b) 7.5 + 7.2 ÷ 3 x 0.2

= 7.5 + 7.2 ÷ 3 x 0.2       First divide

= 7.5 + 2.4 x 0.2              Next, multiply

= 7.5 + 0.48 = 7.98         Finally, add

7.5 + 7.2 ÷ 3 x 0.2 = 7.98

#### So we can add one more operation to our rule for order of operations.

‘of’ → Division  Multiplication  Addition  Subtraction
