Arithmetic Operators (i.e. , +, ×, ÷)
and Constants
and Literal Numbers,
such kind of expression is referred to as an Algebraic Expression.
For example:
(x + y), (5x + 7), (4 + 8y), (4a + 5b), (a  b), (7p  6), (9  4q), (2y  4z), (98c), (a ÷ b), (3p ÷ 4), (10 ÷ 5x), (3p ÷ 4q)
Expressions in Algebra are as :
1). Addition Expression
2). Division Expression
3). Multiplication Expression
4). Subtraction Expression
All these expressions can be studied with examples from the above links.
