- FACT – Forty – the only number in the English Language where the letters are in alphabetic order
- Perfect squares – have 4 sides
- Let’s look at 44 perfect squares
THE SMALLEST and the sneakiest
144 = 12 x 12 441
= 21 x 21
169 = 13 x 13 961
= 31 x 31
Similar, but an obvious
fake
There is something odd about perfect
squares. (even if half of them are even).
They have symmetry. All sorts.
There is symmetry in their numbers. We may
have 10 numerals, but look at them.

No square deal here

The square ends;
1, 9 and Zero too!

Or here

Only 1,4,5,6,9,0 can end a perfect square. 2,3,7,8 never do.
What an odd series the perfect squares make.
0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
Odd?
Just look at the differences or steps from one to the next. 1,3,5,7,9,11,13,15,17,19
