today in class I will teach you how to multiply 15x15, 25x25, 35x35, and so on with no effort. All you do is take the first digit (like 1 from 15) and multiply itwith the number above the digit(which in this case is 2). Next put 25 after it. So 15x15=225 and 25x25=625. Also the 25 goes on all the answer. try some yourself
