Answer 8

Show me what you have done so far

Answer 9

1: 4 / 2 = 2.



2: 10 - 2 = 8.


3: 5 x 8 = 40


3: Anyway, it could be addition first, then subtraction, vice versa. I choose to do addition.

40 + 15 = 55.

390 - 55 = 335

4: easier way, 2 + 2 = 4. Now multiply that by 335. 1340.Still the same answer when you do it the hard way:

335 x 2 = 670

670 x 2 = 1340

Answer 10

Answer 14

You have followed PEMDAS correctly.

Normally some times questions can appear as:

{30 x 4(5 + 2) - 4} - 10.

Don't let the brackets fool you.

Answer 15

But do you understand it?

Answer 16

Answer 17

Great!!!

Answer 18

Do you have any more problems you need help with?

Answer 19

You do PARENTHESIS first before ANY following bracket, then, you do the bracket, then outside the bracket.

Pemdas,

P - parenthesis

E - exponent (skip if not present)

M - multiplication

D - division

A - addition

S - subtraction.
