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
