When we multiply two integers, result is always an integer.
i.e. 4 x 6 = 24
12 x 8 = 96.
a). Multiplying two positive integers gives always positive value . e.g.
-
3 x 7 =21
-
12 X 12 = 144
b). Multiplying two negative integers always gives positive value. e.g.
-
– 5 x – 8 = 40
-
– 11 x -12 = 132
c). Multiplying one positive and one negative integer always gives negative value. e.g.
-
7 x -9 = – 63
-
-3 x 8 = – 24
