Although Jacob hasn't created this video tutorial, he DID bravely share this interesting method with the class during today's maths lesson. Thank you and well done, Jacob! I couldn't have created this tutorial without your help!
This distributive method might be a bit more time consuming than the lattice method or working from right to left, but it's a very interesting and useful method. Why? - I hear you ask! Well, because it shows us in detail HOW multiplication works. It shows us that when we multiply numbers, we ALWAYS multiply every digit in ONE number by every digit in the OTHER number. When computing the answer to ANY multiplication problem, we ALWAYS do this. I wonder if you can see how we do this when we use the lattice method and when we work from right to left??
