Oh, dude, front end estimation is like when you round numbers to make math easier, right? So, if you wanna subtract 189 from 643 using front end estimation, you could round 643 to 600 and 189 to 200, then subtract 200 from 600 to get 400. But like, who needs estimation when you can just do the actual math, am I right?
explain how you would estimate to subtrac 189 from 643
