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 < .
The symbol > means “is greater than.” For example,
12 > 5, 9 > -2, and .
In each case, the symbol “points” toward the smaller number.
