Can someone please help me with math.

I got the first three but that's all I can do for now I have class as well currently. But for number 7 = 0, 8=15, 9= 71 and yeah best of luck on the last three.

7.) 0

8.) 15

9.) 71

12.) 4 / 15

Step-by-step explanation:

7.) 4 + 2 * 12 ÷ 6 - 8 =

Evaluate using PEMDAS

First do parenthesis: There are no parenthesis so we go to the next step

Next we do exponents: There are no exponents so we go to the next step

Next we do multiplication and division ( going left to right )

2 * 12 = 24

24 ÷ 6 = 4

we now have 4 + 4 - 8

The last step is addition in subtraction ( left to right )

4 + 4 = 8

8 - 8 = 0

So 4 + 2 * 12 ÷ 6 - 8 = 0

8.) 9 ÷ 3 + 6 * 2

Evaluate using PEMDAS

There are no parenthesis or exponents so we go to the third step

The third step is multiplication and division ( going left to right )

9 ÷ 3 = 3

6 * 2 = 12

3 + 12 = 15

9 ÷ 3 + 6 * 2 = 15

9.) 3 + 4 - 6 + 2 * 35

Evaluate using PEMDAS

No exponents or parenthesis so go to next step

Multiplication and division first

2 * 35 = 70

3 + 4 -  6 + 70

Addition and subtraction next ( going left to right )

3 + 4 = 7

7 - 6 = 1

70 + 1 = 71

3 + 4 - 6 + 2 * 35 = 71
