Question

How do you simplify `6^3 - 3 times (3^2 times 2) + 5` using order of operations?

Answer 1

We can use the BODMAS rule to solve this.

`167`

Explanation:

The order of operations is given by the BODMAS rule. B=Brackets; O=Of; D=Division; M=Multiplication; A=Addition; S=Subtraction. B i.e. brackets have highest priority and the priority decreases till S i.e. subtraction.

`6^3-3*(3^2*2)+5`

= `6*6*6-3*(9*2)+5)`

= `216-3*(18)+5`

= `216-54+5`

= `216+5-54`

= `221-54`

= `167`
