2 digit multiplication my way: 64 * 69 Step 1: Multiply the tens place. 6 * 6 = 36 36 Step 2: Add 2 zeros next to the product. 3600 Step 3: Multiply the ones place and put the product's last digit in the ones place. 4 * 9 = 36 3636 Step 4: Multiply the first tens place by the second ones place. 6 * 9 = 54 Step 5: Multiply the first ones place by the second tens place. 4 * 6 = 24 Step 6: Add the two products. 54 + 24 = 78 Step 7: Place the last digit of the sum in the tens place, then add. 4416 So 64 * 69 is 4,416.

Thank you for helping me refreshing my math skills. I greatly appreciate it. Sure wish I had a math teacher like you growing up. Chances are I wouldn't have despised math as much. Thanks again!

The problem with a lot of these 'math' videos is that you are 'taught' these algorithms in isolation, and are just expected to memorize them without any prior point of reference, you also aren't really told how they actually work, or why. I think logic is one of the most important areas of mathematics, especially since the majority of its pedagogues are completely devoid of it. I can follow the algorithm just fine but when it comes to carrying it doesn't really make any sense to me.

So this method uses partial products. You multiply each digit of each factor then add them. That's what this method is like, but it's in a different order.

i got it all right but i cant solve 49*54 using your method. it comes out 26136 which is wrong. it should be 2646.

You did it wrong. If the products of the ones places have 2 digits, there should be no blank spaces.

What happens when you do 99*99 and you have a three digit number for the middle value??
Gustavo Chavez (1 month ago)
He should have done 35*63 so that people could understand how to distribute the numbers in that case.
