Please help and can someone explain what a integer is

w = -18

x = -10

y = -2

z = 10

x and z are opposite, x= -10, where as z = 10, Hence x times (-1) equals z.

An integer is a non-fractional number real number. It can be either negative or positive, it simply cannot be a fraction.

"w", "x", and "y" are negative, and hence less than zero.
