Math Square Numbers

Have you seen those square Easter eggs I got one and it was delicious!

This magical maths trick involves square numbers. Remember, you get a square number by multiplying a number by itself. For example 6 x 6 = 36. 36 is a square number.

There is an amazingly quick way of squaring a two digit number which ends in 5. All you have to do is multiply the first digit by the number one more than it, and then put a 25 on the end of your answer.
