Important Formulas for CAT Exam 2025: Number System

Learning the CAT quant formulas can help you understand from the basics. So, here are the important CAT exam formulas for number system: 

Description	Formulas
Difference of Squares	(a + b)(a - b) = a² - b²
Square of a Binomial (positive)	(a + b)² = a² + 2ab + b²
Square of a Binomial (negative)	(a - b)² = a² - 2ab + b²
Square of a Trinomial	(a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca
Sum of Cubes	(a³ + b³) = (a + b)(a² - ab + b²)
Difference of Cubes	(a³ - b³) = (a - b)(a² + ab + b²)
Factorization of a³ + b³ + c³ - 3abc	(a³ + b³ + c³ - 3abc) = (a + b + c)(a² + b² + c² - ab - bc - ca)
Special case for a + b + c = 0	When a + b + c = 0, then a³ + b³ + c³ = 3abc
Sum of first n natural numbers	1 + 2 + 3 + ... + n = n(n + 1) / 2
Sum of squares of first n natural numbers	1² + 2² + 3² + ... + n² = n(n + 1)(2n + 1) / 6
Sum of cubes of first n natural numbers	1³ + 2³ + 3³ + ... + n³ = (n(n + 1) / 2)²
Sum of first n odd numbers	Sum of first n odd numbers = n²
Sum of first n even numbers	Sum of first n even numbers = n(n + 1)
