The part of mathematics in which letters and other symbols are used to represent numbers and quantities in quations.Algebra is about finding the unknown or it is about putting real life problems into equations and then solving them.
In Algebra, you will see:
(1) Algebracic Expressions: eg. x+y, X-5, etc
(2) Algebracic Equation: eg. x + 3 = 10, x + y = 12, etc
A variable is a symbol that stands for a value. For example, in the expression (x+y), x and y are variables.
In an equation: y = x + 3. If the variable x = 4, then y = 7 and so on....
