# 1000 Squared

1000 squared, 10002, is the number you get when multiplying 1000 times 1000. It can also be looked at as exponentiation involving the base 1000 and the exponent 2. The term is usually pronounced thousand times thousand or thousand squared. The square of 1000 is a perfect square because the number is the product of the two equal integers 1000. It can be written as 1000 x 1000 or in exponential form. Read on to learn everything about the number thousand squared, including the useful identities.

10002 = 1000000
1000 x 1000 = 1000000

The inverse operation of squaring thousand is extracting the square root of 1000, explained here. In the next section we elaborate on what is 1000 squared, and there you can also find our calculator.

## What is 1000 Squared

A square is a flat shape with four equal sides; every angle is 90°. Hence, a square with side length 1000 has an area of 1000000.

1000 squared equals the sum of the first 1000 odd numbers:

$\sum_{i=1}^{1000} (2i-1)$ = 1000000

In addition, the number can be calculated from 999 squared using the following identity:

n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
10002 = 9992 + 999 + 1000 = 9992 + 1999 = 1000000

It can be also be computed from 999 squared with this identity:

n2 = 2 x (n − 1)2 − (n − 2)2 + 2
10002 = 2 x 9992 – 9982 + 2 = 2 x 998001 – 996004 + 2 = 1000000

The difference between the perfect square of 1000 and its predecessor, 999, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:

2 x 1000 – 1 = 1999 = 10002 – 9992 = 1000000 – 998001 = 1999

1000 is even, and the square numbers of even numbers are also even: (2n)2 = 4n2.

Squares of even numbers like 1000 are divisible by 4 for $\frac{(2n)^{2}}{4}$ = n2.
