12.57 x 4

Hello, 12.57 x 4 is 50.28 but you have 50.27. Is there a mathematical reason why you chose .27 over .28? Thank you

G'day Ryan.

Can you post up which part of the course specifically you're referring to?

At a complete guess though (its been a while since I watched the course), I'd say that there was probably some rounding done to arrive at '12.57', but the actual figure was carried through when it was multiplied, and the result then rounded to '50.27'?

Ooooooo somebody didn't remember their significant figures from chemistry class :)

LOL in all seriousness, I dont think being off .01 matters really. :D
