ALEKS: Counting significant digits when numbers are multiplied or divided

[@raneenbayyoud]

I never comment on videos but thank you for this clear explanation! I have been on this aleks sections for 3 days and its the last one I needed every time I thought I understood I get smacked with the "row 1: answer incorrect" LOOL so thank you!

Roxi, bless you. I haven't been in school in over a decade and this biology course I'm taking is making me feel like it was a mistake to try to go back. My professor doesn't even lecture, we do this stupid ALEKS thing and go to labs. Thanks for being a great teacher

I'm so sorry that you're having a rough start with your first quarter back but oh my gosh - you did not make a mistake! Keep at it! Anytime you take 10 years off from something, it's going to be a bit bumpy when you start up again, but you'll get back in the groove and you'll do great! Hang in there - I know you can do it!

How are we able to reduce 523 to 520? Is there a rule that allow us to do that or something else?
