Meaning of Inequality:
An inequality is a sentence that says that two values are not equal. E.g. if a is not equal to b, we can write a ≠ b (where ≠ means “is not equal to”). Therefore, inequalities are used to compare the relative sizes of values like integers, variables, etc.
Inequality Symbols:
The following are inequality symbols
\(\scriptsize > \:\) (“is greater than”)
e.g
\( \scriptsize 5 > 3 \) means 5 “is greater than” 3
\( \scriptsize y > 10 \) the values of y include 11, 12, 13, 14 ……
\(\scriptsize < \: \) (“is less than”)
e.g
\( \scriptsize 3 < 5 \) reads 3 “is less than” 5
\( \scriptsize y < 10 \) the values of y include 9, 8, 7, 6 ……
