PRESENTATION OUTLINE
MULTIPLICATION OF INTEGERS
MU
- Positive x positive = positive
- Negative x positive= negative
- Positive x negative = negative
- Negative x negative = positive
The opposite number is the same distance from zero but opposite direction
Positive x positive = positive
Negative x negative = positive
Negative x positive = negative
Positive x negative = negative
EXAMPLE
- 3x (-4) = -12
- -8 x (-2)= 16
- -7 x 3 = -21
- So
- 4 (d) (-2) = -2
- -10 (d) (-5) = 2
- -8 (d) 4 = -2
