Multiply 7 and 5 to get 35 (use memorization, fingers, or your multiplication table). Write down the 5 (from 35) and write a small 3 down that will signify that you're going to use that as a carry. Now multiply 3 and 5 to get 15. Now add that last carry of 3 to 15 to get 18 Now write the 18 just to the left of that first 5 you wrote down to get 185 Visually, you might see it as this .37 ...5 --- 185
