Algebraic Expressions

Algebraic expressions are mathematical expressions containing variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division.

Exponents are used to represent repeated multiplication of the same number, while powers are the result of using exponents. For example, in the expression 2^3, 2 is the base and 3 is the exponent, and the result is 8.

The focus of the chapter is to introduce students to the concept of algebraic expressions, exponents, and powers, and to help them understand how to work with these mathematical concepts in various problem-solving scenarios.
