Equation
Equation are the basic mathematical tool
for solving real-world problem
To solve the problem, we must know
how to construct equation that model
real-life situations.

inequalities
• An inequality says that two values are not equal.
a ≠ b says that a is not equal to b
There are other special symbols that show in what way
things are not equal.
a < b says that a is less than b
a > b says that a is greater than b
(those two are known as strict inequality)
a ≤ b means that a is less than or equal to b
a ≥ b means that a is greater than or equal to b.
