WORKSHEET 1.20: DIVIDING INTEGERS

-------------------------------------------------------------------------------------

When dividing integers, determine the sign of the quotient by following the rules below:

1. If both the divisor and the dividend are positive or both are negative, the quotient is
   positive.


2. If either the divisor or the dividend is positive and the other is negative, the quotient is
   negative.


3. If 0 is divided by any number, the quotient is 0.


4. If any number is divided by 0, there is no solution because division by zero is undefined.

EXAMPLES

− 72 ÷(−8)= 9 −^63
