Two numbers that multiplied equals +90 are: +9 and +10

Two numbers that multiplied equals -88 are: -11 and +8

Two numbers that multiplied equals +70 are: -10 and -7

Two numbers that multiplied equals +40 are: -8 and -5

Two numbers that multiplied equals -33 are: -3 and +11

Two numbers that multiplied equals -20 are: +5 and -4

Two numbers that multiplied equals -18 are: -6 and +3

Two numbers that multiplied equals +9 are: -1 and -9

Two numbers that multiplied equals +6 are: +1 and +6

Two numbers that multiplied equals -6 are: +3 and -2

Two numbers that multiplied equals 0 are: +7 and 0
