left to right

Why is it important to know PEMDAS?

So that everyone is solving the problem in the same way

Identify & Fix My Mistake

100

4 + 5 + 7 - 3 * 2 = 26

4 + 5 + 7 - 3 x 2 = 10

Evaluated the full expression from left to right

200

6 + 100 / 10 + 9² * 4 = 88

6 + 100 / 10 + 9² * 4 = 340

Evaluated 9*2 instead of 9²

300

15 + (20 - 4)² - 6 = 153

15 + (20 - 4)² - 6 =265

Distributed the exponent

400

(30 + 3 / 3) * 3 - 2 = 31

(30 + 3 / 3) * 3 - 2 =91

Added 30+3 first

500

2 + (9 + 4³ - 70) + 30 / 6 = 22

2 + (9 + 4³ - 70) + 30 / 6 =10

Added 30 before dividing 30 by 6
