It is a lot of numbers and letters, combined together with various mathematical operations and functions. Operations such as addition, subtraction, multiplication division, exponentiation etc; functions such as trigonometric ones, logarithms, factorials, etc.
An expression cannot have an equals sign (or a less than or more than sign) because then it becomes an equation (inequality).
So 3x2 + 2y/sin(x) - 23-x is an expression.
