In Mathematics, an Algebraic Expression is an expression built up from integer constants, variables and the algebraic operations.
An Algebraic Equation can be defined as a Mathematical statement in which two expressions are set equal to each other. In simple words, equations mean equality.
Algebraic Equation is a Mathematical sentence with an equal sign (=) which shows that two expressions or both sides are equal.
The symbol = is read “equals” and separates an equation into two parts:
the left member and the right member.
Common words Translated as = equal or equals, is/are, is equal to, result is, yields.
Direction: Write an expression to represent each of the following.
