Question

What is 9 * 27 + 2 + 31 * 28

Answer 1

PEMDAS lets us know what operation we should carry out first.

because M (multiplication) comes before A (addition) we need to multiply our numbers first

9 · 27 + 2 + 31 · 28

243 + 2 + 868

now we can add

243 + 2 + 868

245 + 868

1113

hope this helps

Answer 2

You have to use PEMDAS

PARENTHESES: ( )

EXPONENTS: A²

MULTIPLICATION: ×

DIVISION: ÷

ADDITION: +

SUBTRACTION: -

The order for subtraction and division doesn't matter. When there is subtraction and addition, you do the one that comes first.

First is multiplication:

$9 \times 27 = 243$

Do the multiplying at the end:

$31 \times 28 = 868$

Here is your new equation:

$243 + 2 + 868$

Add:

$243 + 2 + 868 = 1,113$

Your answer is 1,113
