1. = ?
A quicker way of writing this is 4 x -3, 4 lots of -3. So 4 x -3 = -12.

2. = ?
So we know that 4 x -3 = -12 and we know that 3 x -4 = -12. This is showing us that if we multiply two numbers, and one of them is negative, the result, or product, is also negative.

3. 3 × -8 = ?
-4 × 6 = ?
How many examples can you find for the last one? Any decimals?
? × ? = -24

4. -3 × ? = 12
We know that -3 x 4 would be -12, so how can we get 12? The answer is it must be a negative number, -3 x -4 = positive 12. When you multiply two negative numbers, the result is positive.

5. -5 × -4 = ?
-4 × -3 = ?
There are two possible answers for the value of a, what are they?
a × a = 25

6. A) -2 × 7 = ?
F) -3 × -3 × 4 = ?
B) -2 × -4 = ?
G) -1 × 4 × -4 = ?
C) 5 × -7 = ?
H) -7 × 2 × -3 = ?
D) -3 × ? = 18
I) -3 × -3 × -3 = ?
E) ? × -5 = 20
J) -2 × 5 × -1 = ?

7. A) -2 × 7 = -14
F) -3 × -3 × 4 = 36
B) -2 × -4 = 8
G) -1 × 4 × -4 = 16
C) 5 × -7 = -35
H) -7 × 2 × -3 = 42
D) -3 × -6 = 18
I) -3 × -3 × -3 = -27
E) -4 × -5 = 20
J) -2 × 5 × -1 = 10

8. -20 ÷ 4 = ?
This is the same question as asking, 4 lots of what make -20? We want to split -20 into 4 equal parts, so the answer must be -5. It follows the same rule as multiplication. If one number is negative, the quotient is negative. If both numbers are negative, the quotient is positive.

9. -10 ÷ 2 = ?
15 ÷ -3 = ?
-18 ÷ -6 = ?

10. A) -21 ÷ 7 = ?
F) (-3 × -6) ÷ 9 = ?
B) -15 ÷ -3 = ?
G) -2 × (8 ÷ -4) = ?
C) 25 ÷ -5 = ?
H) (-12 ÷ 2) × -3 = ?
D) -30 ÷ ? = -5
I) (-2 × 3) ÷ -3 = ?
E) ? ÷ -5 = 20
J) (-20 ÷ 5) × -1 = ?

11. A) -21 ÷ 7 = -3
F) (-3 × -6) ÷ 9 = 2
B) -15 ÷ -3 = 5
G) -2 × (8 ÷ -4) = 4
C) 25 ÷ -5 = -5
H) (-12 ÷ 2) × -3 = 18
D) -30 ÷ 6 = -5
I) (-2 × 3) ÷ -3 = 2
E) -100 ÷ -5 = 20
