Use inequality symbols

 

The statement 4 + 2 = 6 is

an equation; it states that two quantities are equal. The statement 4 ≠ 6

(read “4 is not equal to 6”) is an inequality, a statement that two quantities

are not equal. When two numbers are not equal, one must be less than the

other. The symbol <  means “is less than.” For example,

8 < 9, -6 <, 15, -6 < – 1, and 0 < \frac{4}{3} .

The symbol >  means “is greater than.” For example,

12 > 5, 9 > -2, and \frac{6}{5} > 0 .

In each case, the symbol “points” toward the smaller number.
