200

What does it mean to combine like terms 

add like groups  (3x + 4 are not like groups)

300

Which symbol is the grouping symbol in mathematics?

Parentheses

400

What is the property  5+3=3+5

(Associative, Commutative, Identity, Inverse, distributive)

Commutative

500

What is the property?  5 + -5 = 0

Fix my Mistake

100

9 - 3 x 2=12

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

200

5 ² + 1=11

5 ² = 25, not 10. Correct Answer is 26.

300

3² - 6 = 0

3 ² = 9, not 6. Correct answer is 3

400

4 + 5 + 7  + (-3)² = 7

(-3)² = -3 x -3 = 9. Correct answer is 25 .

500

10 ³  = 30

10 ³  = 10 x 10 x10, which is 1000, not 30.

Simplify #1

Simplify #2

100

12x + 7 - 3x - 7

9x

200

3(2x - 9)

6x - 27

300

5 + 3(x + 5)

3x + 20

400

3(2x - 4) + 3x

9x - 12

500

- 4(x - 12) + 2

-4x + 50
