The first 6 perfect squares are 1,4,9,16,25, and 36, When you are doing perfect squares, you multiply by itself. Thank you Mrs.Pelfrey By: Camila
OK. Got it. Now what to do with the list ?

1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
The squares of the numbers 32, 33, 34,...,44 the square of the first number 32 is 1024 the square of the last number 44 is 1936

The smallest perfect squares that end with 9 are 9 (the square of 3) 49 (the square of 7). Their difference is 40.

The first five perfect squares are: 1, 4, 9, 16, 25
The first three perfect squares that end in 4 are 4, 64, and 144. These correspond to the squares of the integers 2 (2² = 4), 8 (8² = 64), and 12 (12² = 144). Perfect squares that end in 4 must be the squares of integers ending in either 2 or 8.
For an expression to be a difference of two squares, it must be in the form (a^2 - b^2), where both (a) and (b) are real numbers or algebraic expressions. This means that the first term must be a perfect square, and the second term must also be a perfect square. The expression can then be factored as ((a - b)(a + b)).

The sum of the squares of the first 100 natural numbers [1..100] is 338350, while the sum of the first 100 natural numbers squared is 25502500.
To cut brownies into perfect squares, first let them cool completely. Then, use a sharp knife to make straight cuts, wiping the knife clean between each cut. You can also use a ruler to measure and ensure even square sizes.

The difference is... so you can tell apart weather that is your piece or not! Also the white piece always goes first unless you modify the game.
