So my instructor is trying to get use familiar with significant figures and I can't figure this one out.
107.838 - 2.113x10^2 + 5.623x10^3
I have inputted 5519.538, and 5520. It keeps coming back with "incorrect significant figures". Please help!
Got it but don't know why. 5.520x10^3 is the correct answer, but how is that different from the 5520? I hate sig figs.
