MCAT Math Without a Calculator Simplified with Shortcuts

[@dr.dariapanina6984]

6:44 it says 90 degrees sine is 0.9 instead of 1 (or 65 degrees )

[@Leah4sciMCAT]

You're right, sorry for any confusion this caused. You're correct that the exact sin of 90 equals 1. Good catch, thank you!

How does 1.7x10 round to 1 instead of 2? And how does 8.3x10 round to 1x10? Really wish she explained that a bit more. I was lost at that point.

[@Leah4sciMCAT]

Since it was a multiple choice question, we were trying to round our answers to easier numbers like 1 or 10 in order to figure out which answer choice was closest to our estimate of 1 x 10^-5. In the end, we figured that 1.7x10^-5 rounds DOWN to 1 x 10^-5 while 8.3x10^-6 rounds UP to 1 x 10^-5. Which answer did we choose? Well, since our estimated value was calculated by rounding UP, we knew that our actual answer should be lower than what we estimated. Making our answer D.
