## What are Expressions?

An Expression is a number, a variable, or a combination of numbers, variables, and operation symbols.

For example,

• x + 3
• y – 10
• 19 x 3

An expression can be of one of the following two types:

## Numerical expression

This is an expression that consists only of numbers. For example,

• 13 + 6
• 15 – 5
• 16 x 15

## Algebraic expression

This is an expression that consists of only variables or variables and numbers together. For example,

• 6 + y
• x – 12
• 15xy
