Para multiplicar ou dividir números inteiros, a princípio, as operações devem ser realizadas considerando apenas seus valores.
O resultado será positivo ou negativo, dependendo apenas dos sinais serem iguais ou diferentes.

Ao multiplicar ou dividir números inteiros de mesmo sinal o resultado será sempre positivo.
3 x 2 = 6
-3 x (-2) = 6
10 : 2 = 5
-10 : (-2) = 5
4
Nos casos de multiplicar ou dividir números inteiros com sinais diferentes, o resultado será sempre negativo.
5 x (-6) = -30
-4 x 7 = -28
-28 : 4 = -7
30 : (-5) = -6
