The easy way is the multiply 4 times 8, and then add a 0 at the end. So 4 times 8 is 32, and the answer is 320.

Hey there!

2 ways to do it:

1. Add 80 four times and you'll get= 320

2. If you know your math facts, then you would know what 8*4 is which is 32 and then add how many zeros there are and you'll get 320

Hope this helps!
