Simple Expressions do not have equal signs, equations do.

Detailed An expression does not equal to any value. An equation on the other hand has two expressions that are equivalent.

For example,

5+5
would be considered an expression

5+5 = 6+4
would be considered an equation, because it contains an equal symbol.
