This week for math my math group has been working on big multiplication and how to figure it out. Here is my way of figuring out big multiplication
First you break it down, take the ten from 18 and multiply it by the 9 (If instead of a single digit like 12 multiply the 10 and then the 2)
then take the 8 and multiply it by the 9 after add the two answers together and there your answer
Maybe you should give this a go
