Square Numbers ```Name: Brianna Status: student Age: N/A Location: N/A Country: N/A Date: N/A ``` 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. Vince Calder 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.
