What do you do first?

100

2 x 3 + 6

2 x 3

200

3 + 4 x 2 - 8

4 x 2

300

2 + | 2 - 8 | x 2

2 - 8

400

2 x (2 - 1 x 10) - 2

1 x 10

500

|2- 3| x 5

2-3

Fix my Mistake

100

9 - 3 x 2=12

Correct answer is 3. Do x then -, not - then x.

200

1 - 5 = 4

1 - 5 = -4

300

3 X 0  + 6 = 9

Didn't multiply 3 x 0 

400

4 + 5 + 7 - 3 x 2 = 26

You need to follow PEMDAS and do x first. Correct answer is 10.

500

10 X 10 X 10 = 30

10 X 10 X 10 = 1000 not 30
