What are Expressions?
An expression is a combination of numbers, variables, operators, and functions. It is a mathematical statement that represents a numerical value or a specific mathematical operation.
An expression can be written in various forms, such as:
Numerical expressions: These are values that can be directly assigned to a variable, such as 5 + 2 or 3x + 1.
Variable expressions: These are variables, which are represented by letters, such as x, y, or z.
Operator expressions: These combine numbers, variables, and operators using mathematical operators, such as addition, subtraction, multiplication, and division.
Function expressions: These combine numbers, variables, and functions using function notation, such as f(x) = x^2 or g(t) = 3t + 1.
Expressions can be combined and manipulated using the laws of arithmetic, such as addition, subtraction, multiplication, and division. They can also be used to represent mathematical relationships between variables and solve problems
