Distributive Property

100

Solve:

8(a + 4)

8a + 32

200

Solve:

10(20 - 15)

200-150 = 50

300

Use the distributive property to rewrite an expression that is equivalent to:

12 + 4x

4(3 + x)

2(6 + 2x)

400

Solve:

0.4(5-2.5a)

2-a

500

Solve:

2x(3y + 4z - 5yz)

6xy + 8xz - 10 xyz

Finding Percent

100

Solve for a:

25% of 100 = a

25% = 1/4

So, 1/4 of 100 = 100/4 = 25

200

Solve for a:

125% of 240 = a 

100% = 240

25% = 60 (240 ÷ 4)

125%= 300

300

Solve for a:

32% of 700 = a

100% = 700

10% = 70

1%= 7

So 32% = 210 + 14 = 224

400

Solve for a:

25% of a = 8

8 ÷  0.25 = 32

500

Solve for a:

60% of a = 43.2

a = 43.2 ÷  0.60

a = 72

Exponents

100

Write in expanded form:

12³

12 x 12 x 12

200

Solve:

12³

12 x 12 =144

144 x 12 = 1728

300

Solve:

6 + 4²

6 + (4 x 4)

6 + 16 = 22

400

Solve:

8² + 3³ + 2⁴

64 + 27 + 16 = 107

500

Write in expanded form:

a³ + b² + c⁵

(a x a x a) + (b x b) + (c x c x c x c x c)

Solving Equations

100

Find the value of y:

3 + y = 12

y = 12-3 

y = 9

200

Find the value of y:

4y = 64

y = 64 ÷ 4

y = 16

300

Find the value of y:

y - 8.79 = 26.51

y = 26.51 + 8.7

y = 35.30

400

Find the value of y:

y ÷ 4 = 93

y = 93 x 4

y = 372

500

Find the value of y:

5^y = 15,625

y = 6

(5 x 5 x 5 x 5 x 5 x 5) = 25 x 25 x 25

Order of Operations

100

14 - 2 x 5 = ?

? = 14 - 10

? = 4

200

10 - 7 + 3 x 2 = ?

? = 10 - 7 + 6

? = 3 + 6

? = 9

300

2 + 3² ÷ (3 + 6) = ?

? = 2 + 9 ÷ 9

? = 2 + 1 

? = 3

400

3(12 - 5 x 2) = ?

? = 3(12 - 10)

? = 3(2)

? = 6

500

1/2(2 + 4)² - (3² - 5) = ?

? = 1/2 (36) - (4)

? = 18 - 4

? = 14
