⟩ Do you know what is algebra?
Algebra is one of the fields of maths, which uses symbols and letters to represent numbers, point and objects, as well as relationship between them. It is used to know the unknown variables.
For example, you have lost 5 pens, and you are left with 10 pens now, to know the total number of pens you had it. You will use algebraic equation.
X -5 = 10
X= 10+5 = 15 which is the total number of pens you had.
