Description: Sal solves multiplication comparison problems. Created by Sal Khan. So they're saying that the number 36, we'll type 36, is equal to 3 times 12. So to get this little star thing, which is normally when you're typing on a computer how you show multiplication, to get that you have to press Shift and the number 8. So this could be read as 36 is equal to 3 times 12, or 36 is 3 times as large as 12.
