Variable Expressions Worksheets

What are Variable Expressions? Mathematics is full of different forms of expressions and concepts. One of the most common expressions in mathematics is a variable expression which is widely used in mathematics to solve problems. Do you want to know what a variable expression is? First, understand what a variable is? A variable is an alphabetical letter used in a mathematical expression or equation to represent a number. Now, do not let the fact that it's a number confuse you. Since it is used to express a number, you treat it like a number while solving the expression. To be more precise about a variable, it is a symbol that hides in itself an unknown value. You can use any symbol as a variable, but most commonly, you will find these letters being used as variables, a, b, c, d and x. An example of a variable expression is 1000x. Here x is a variable that represents an unknown value being multiplied with 1000 and can only be found out when you substitute x with a value.
