Algebra Formulas for SSC CGL 2023

Algebra is a set of symbols made up of both letters and numbers that may be used to calculate any unknown value. An algebraic equation or expression is created by combining the usage of numbers, characters, matrices, and vectors. In the algebraic expression, there are numbers with known values and letters with unknown values. Algebra formulas for SSC are utilised instead of numbers and letters to find the values of unknowable quantities.

Below we have provided you all with the important Algebra formulas for SSC CGL under various categories. Go through these formulas and memorize them, we are sure that these formulas will surely help you in the upcoming SSC CGL 2022-23 tier 2 Examination.

Algebra Formula for SSC CGL: Natural Number

  1. (an – bn )= (a – b)(an-1 + an-2b+…+ bn-2a + bn-1)
