    Tricky Maths Puzzle! need help!!

    You have got to multiply two numbers together like 3x5=15 but you cant use multiply.
    You have to get to 15 by using the numbers 3 and 5 by the means of x squared, adding and subtracting.
    You cant multiply the numbers or divide!

    Any suggestions will be good!!
    Thanks

    You'll have to give us more information than this. I have no idea what you're trying to accomplish.
