Didn't use the template because it didn't make sense to do so for my question..
Simple question here regarding significant figures. I am working through a textbook and in the answer section they often seem to round off to odd numbers which makes no sense to me. I decided to ignore it at first because I am so sure that I am doing it correctly, I mean... I learned to round in grade 2 . But it seems to happen a lot and I figure that the person writing the text wasn't an idiot so...
for [tex]\frac{1.20kg}{2.99x10^{-26}kg}[/tex] they have their answer as [tex]4.02x10^{25}[/tex]. I say that its [tex]4.01x10^{25}[/tex]
Who's right? and why if I am not right.
