I have found out how to find square numbers without multiplication. You have to add an odd number onto the previous square number. the odd number increases by two every time you go up a square number. for example to go up from 1 to 4, you have two add 3, and to go up from 9 to 16 you have to add 7, so in order to find the next number you have to add 9. homepage.
