Division:

Division of signed numbers might be performed using the subsequent rules:

Rule 1: The quotient of any two numbers with like signs is positive: (+)/(+) = (+) or (-)/(-) = (+)

Rule 2: The quotient of any two numbers along with unlike signs is negative: (+)/(-) = (-) or (-)/(+) = (-)

Rule 3: Zero divided by any number not equal to zero is zero.

Examples:

a) 0/-5 = 0 Apply rule 3.

b) -3/-1 = +3 Apply rule1.

c) -4/+2 = -2 Apply rule 2
