Let's do one with bigger numbers!
Get it set up!
|
Start at the bottom and add down the diagonal stripes... But, look what happens when we hit the yellow diagonal stripe!
|
|
We get a two digit answer... So, we just need to carry into the next diagonal stripe. It's the same thing we do with regular addition!
|
|
Now, finish it off!
|
Pretty cool, huh? Try some yourself! You can check your answers using a calculator or the regular way of multiplying.
