-9998 squared equals the sum of the first -9998 odd numbers:

In addition, the number can be calculated from -9999 squared using the following identity:

n^{2} = (n − 1)^{2} + (n − 1) + n = (n − 1)^{2} + (2n − 1)

(-9998)^{2} = (-9999)^{2} + -9999 + -9998 = (-9999)^{2} + -19997 = 99,960,004

It can be also be computed from -9999 squared with this identity:

n^{2} = 2 x (n − 1)^{2} − (n − 2)^{2} + 2

(-9998)^{2} = 2 x (-9999)^{2} – (-10000)^{2} + 2 = 2 x 99980001 – 100000000 + 2 = 99,960,004
