Multiply and Divide Integers

When we multiply two integers having different signs, the result will be a negative integer
Or,
- a x b = - c or
a x - b = - c

When we multiply two integers having the same sign, the result will be a positive integer

Or,
a x b = c or
- a x - b = c

Product of any integer and zero is zero.

or, a x 0 = 0 , where 'a' is any integer

In x ÷ y = z,
x is called the dividend,
y is called the divisor, and
z is called the quotient

When we divide two integers having different signs, the quotient will have a negative sign.
Or,
- a ÷ b = - c or
a ÷ - b = - c

When we divide two integers having the same sign, the quotient will have a positive sign.
Or,
a ÷ b = c or
- a ÷ - b = c

Zero divide by any integer equals 0
Or, 0/a = 0 (where 'a' is any integer)
