The letter "x" can mean several things in mathematics. Firstly, it is the x-axis of a graph. Secondly, it can be a stand-in for a missing number that is to be solved for.

In mathematics, a number written in superscript is used to represent an exponent. In the case of x2, this can be read as "x to the power of two" or simply "x squared".

An exponent is a way of noting how many instances of a value should be multiplied by itself. For example, 34 can also be expressed as 3 × 3 × 3 × 3. In the case of x2 then, this is just two occurrences of the variable "x" being multiplied together.
