The rule for multiplying and dividing is very similar to the rule for adding and subtracting.
a) 5 × -4
b) -40 ÷ -8
a) We have +5 and -4. The signs are different, so the answer will be negative. So, +5 × -4 = -20
b) We have -40 and -8. The signs are the same, so the answer will be positive. So, -40 ÷ -8 = 5
