- coryrc 5y agoEven on paper it's far simpler (1000000-1)*5 => 5000000-5 => 4999995 Learning to find these patterns early sets up students for having an easier time with algebra later. Algebra is just rearranging equations. I don't understand, but students do struggle with going from "12/3=?" to "3*X=12 solve for X". We can't keep failing so many students every year and expect our country to hold together.
