What is 990 Squared?

A square is a flat shape with four equal sides; every angle is 90°.

Hence, a square with side length 990 has an area of 980,100.

990 squared equals the sum of the first 990 odd numbers:


In addition, the number can be calculated from 989 squared using the following identity:

n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
(990)2 = 9892 + 989 + 990 = 9892 + 1979 = 980,100

It can be also be computed from 989 squared with this identity:

n2 = 2 x (n − 1)2 − (n − 2)2 + 2
(990)2 = 2 x 9892 – 9882 + 2 = 2 x 978121 – 976144 + 2 = 980,100

The difference between the perfect square of 990 and its predecessor, 989, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:

2 x 990 – 1 = 1979 = (990)2 – 9892 = 980,100 – 978121 = 1979

990 is even, and the square numbers of even numbers are also even: (2n)2 = 4n2.
