Inequality Symbols and Meanings
In mathematics, we use the equal sign, = to show that quantities are the same. However, very often, quantities are different, or unequal. The inequalities symbols are as follows:
Take a and b to be any number points on number line below:
If a = +3 and b = +3
a and b have the same position on the number line.
Hence, a = b
But if a = 1
and b = −4
then a > b
or b < a
A linear inequality is an open sentence with an inequality sign.
