What are all the squared numbers up to 100?

Answer 1

A square number is the result of a number (often understood to be an integer) multiplied by itself.

In this case, just multiply numbers by themselves to get the square numbers:

0 x 0 = 0

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

etc., up to:

10 x 10 = 100
