(show all working)

6.218 - ensure they have been lined up

500

(16 divided by -4) - (-7)

(Show all working, no calculator)

(-4) - (-7) = -4 + 7 = 3

Fractions

2/7 + 4/7 = 

6/7

200

5/14 + 2/14 = 

(simplify, no calculator)

7/14 = 1/2

300

2/3 x 3/10 = 

(simplify, no calculator)

6/30 = 3/15 = 1/5

400

1/4 + 3/5 =

(show working, simplify)

5/20 + 12/20 = 17/20

(need common denominators)

500

1 & 1/3 divided by 2/5 =

(no calculator, show all working)

4/3 divide 2/5 = 4/3 x 5/2 = 20/6

10/3 = 3 & 1/3

y⁹ divide y⁴

y⁵

(division with same base, powers are -)

300

y² x y⁶ = 

y⁸

(multiplication with the same base, powers are +)

400

(y⁰ + y⁰) x 6

(anything to the power of 0 = 1)

500

3y³ x 2y⁶ = 

6y⁹

(multiply numbers, index laws, 3 + 6 for powers)

One Step Equations

100

x + 3 = 8

Solve for x (show working)

5

(-3 to both sides, solve for x)

200

2x = 12

Solve for x (show working)

x = 6

(divide both sides by 2)

300

x/5 = 11

Solve for x (show working)

x = 55

(multiply both sides by 5)

400

7x - 4x = 9

Solve for x (show working)

x = 3

(Like terms, 7x-4x=3x, divide both sides by 3)

500

3x - 7x = 12

Solve for x (show working)

x = -3

(Like terms, 3x-7x=-4x, divide both sides by -4)

Two Step Equations

100

2x + 3 = 7

Solve for x (show working)

x = 2

(-3 from both sides, divide 2 both sides)

200

x/2 - 5 = 15

Solve for x (show working)

x = 40

(+5 to both sides, multiply both sides by 2)

300

9a + 7 = 34

Solve for a (show working)

a = 3

(-7 from both sides, divide both sides by 9)

400

2x + 13 - 5x = 1

Solve for x (show working)

x = 4. (like terms, 2x-5x=-3x, minus 13 from both sides, divide both sides by -3)

500

8 - 3y = -7

Solve for y (show working)

y = 5

(-8 from both sides, divide both sides by -3)
