What are the frist 12 square numbers?

Answer 1

A square number is just a number squared. I'll list 0 here, but most people would start at 1.
02 = 0 x 0 = 0

12= 1 x 1 = 1

22= 2 x 2 = 4

32= 3 x 3 = 9

4

2= 4 x 4 = 16

5

2= 5 x 5 = 25

6

2= 6 x 6 = 36

7

2= 7 x 7 = 49

8

2= 8 x 8 = 64

9

2= 9 x 9 = 81

10

2= 10 x 10 = 100

112= 11 x 11 = 121

122= 12 x 12 = 144

If you are talking about integers, starting at 1, the first twelve square numbers are:

1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144
