An algebraic expression is a mathematical phrase that can include numbers, operations symbols, and most importantly variables.
Because variables are important elements, algebraic expressions are sometimes called variables expressions.
|Mathematical phrase||Algebraic expression|
|Six more than a number||x + 6|
|The difference of twelve and a number||12 - x|
|The product of a number and negative 4||x(-4)|
|A number divided by another number||x/y|
|Twice a number plus three||2x + 3|
|Two subtracted from a number||x - 2|
An algebraic expression does not have an equal (=) sign
For example, x + 8 - y = 12 is not an algebraic expression.
