squaring any two digit number (ex: 23,56,89,62......)
" It is simple"
Rule: Square the tens digit and affix the square of the units digit to the result. If the square of the units digit is less than 10, precede it with a zero(0) before affixing it to the square of the tens digit . Double the product of the digits of the given number. Add the units digit of this product to the tens digit of the previous number and add the tens digit of the product to the hundreds digit of the previous number.
Example: Square 63.
square the tens digit, 6*6=36
square the units digit, 3*3=9
Precede this with a zero, since it is less than 10, and affix it to the result above.
3609
Double the product of the digits, (6*3)*2=36
Ad the units digit , 6, to the tens digit of 3609 and add the tens digit , 3, to the hundreds digit of this number.
