Question

Eva l u t a e 7^2-3+9×8÷2=

Answer 1

We use the PEMDAS rule to answer our question which says in an arithmetic operation the order of precedence is the following.

parenthesis > Exponents > Multiplication/ division > addition/ subtraction.

Having that in mind, we see that there is no parenthesis in our expression, and therefore, we proceed to simplify the exponents. Doing this gives

`49-3+9*(8)/(2)`

Next up is multiplication and division, meaning 9 × 8 ÷ 2 is to be simplified.

Since, 9 × 8 ÷ 2 = 36, the expression becomes

`49-3+36`

Now we do addition and subtraction from left to right and we get

`49-3+36=82`

Hence, our expression simplifies to 82.
