Step-by-step explanation:

Algebraic expression

An algebraic expression in mathematics is an expression formed up of variables and constants. It has algebraic operations (addition, subtraction, multiplication, division, etc.).

Examples:

• a + b^2 +c^3
• y - z
• 3q - 2r - s

Equation

An equation a statement that the values of two mathematical expressions have the same value (specified by the sign =).

Examples:

• P = 2l + 2w
• A = s^2
• V = lwh/3

Inequalities

Inequality is an association that makes a non-equal comparison between two numbers or other mathematical expressions.

Examples:

• x < 50
• i + l > y + s + m
• s < mh
