Question:
What is a square number? Is one a square number?

Replies:
Square numbers are those positive integers that form a square
if you put pebbles in the sand to form a square. The first
square number is 4 -- four pebbles at the vertices of a square,
the next square number is 9 -- a set of 3x3 pebbles, the next is
16 -- a set of 4x4 pebbles -- and so on. Square numbers have
special properties in the area of mathematics known as "number
theory". I do not think that '1' is considered a square number.

Brianna,

Multiply any integer by itself to yield a square number.
Square numbers
are:

0x0=0
1x1=1
2x2=4
3x3=9
4x4=16

And so on.
