(a + b)² = (a² + b² + 2ab)

(a – b)² = (a² + b² – 2ab)

(a + b)² = (a² + b² + 2ab)

(a + b)(a – b) = (a² – b²)

(a³ – b³) = (a – b)(a² + ab + b²)

When a + b + c = 0, then a³ + b³ + c³ = 3abc

(1² + 2² + 3² + ….. + n²) = n ( n + 1 ) (2n + 1) / 6

1 + 2 + 3 + 4 + 5 + … + n = n(n + 1)/2

(1³ + 2³ + 3³ + ….. + n³) = (n(n + 1)/ 2)²

Sum of first n odd numbers = n²

Profit % = Profit/(C P)×100

Profit/Gain = (S.P.) – (C.P.)

C P = 100/(100+gain %)×S P

S P = (100+gain % )/100 ×C P

Loss % = Loss/(C.P.)×100

C P = 100/(100-loss %)×S P
