How do you do multiplication? - Answers

Multiplication is broken down into steps: # Multiply # Put zeros # Add # Answer Here is an example: 12 x 18 = ? * 1 * 12 * x 18 * ------------- * 6 First do 8 x 2, or up and down multiplication, which is 16. Put the 6 below the 8, and carry the 1 over to the tens column, which is over the 1. * 1 * 12 * x 18 * --------- * 96 Then, do diagonal multiplication. Do 8 x 1. Then add the 1 you carried over. Put that below the 1 or tens column. You're done multiplying with the 8. Cross out the carried over numbers. * 1 * 12 * x 18 * -------- * 96 * 120 Put a zero down under the 6 in 96. Then do the same thing you did above. 2 x 1 = 2 and 1 x 1 = 1. * 1 * 12 * x 18 * --------- * 96 * 120 * --------- * 216 Finally, add up the numbers below the problem. 96 + 120 = 216 The answer is 216. 12 x 18 = 216. That's how you do multiplication.Multiplication you just have to multiply them that's all you need to do
