Front

Simplify: 2 + 3 x 4

Back

14 (First multiply 3 x 4 = 12, then add 2)

Front

Simplify: (5 + 3) x 2

Back

16 (First add 5 + 3 = 8, then multiply by 2)

Front

True or False: 6 + 2 x 3 = 12

Back

False (Correct answer is 12, but the order of operations gives 6 + 6 = 12)

What is the result of 10 - 2 x 5 + 3?

Back

3 (First multiply 2 x 5 = 10, then 10 - 10 + 3 = 3)
