Bot GPT 3.5 In math, an expression is a combination of mathematical symbols, numbers, variables, and operators that represents a value. It can consist of numbers alone, variables alone, or a combination of both, along with arithmetic operations such as addition, subtraction, multiplication, division, exponentiation, and others.
For example, 2 + 3 is an expression representing the sum of 2 and 3. Another example is 4x - 7, where x is a variable, representing the difference between 4 times x and 7.
Expressions can be used to perform calculations, solve equations, or serve as building blocks for more complex mathematical concepts.
