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
