Algebraic expression
consists of sums and/or products of numbers and variables
An algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. It does not have an equal sign, and the variables can be replaced by actual values to evaluate the expression. For example, 3x + 5 is an algebraic expression, where 3 and 5 are constants, x is a variable, and + is an operation. We can substitute x = 2 to get 3(2) + 5 = 11. The value of the expression depends on the values assigned to the variables. Algebraic expressions are commonly used in mathematics to represent real-world problems such as distance, time, and speed.
