OP
IIRC, if you round something once, and round it again, and over and over again, eventually you'll spread the error throughout your calculations and you have no idea how off your numbers are, because each value has an experimental error associated with it. So you use standards of significant figures to keep your numbers somewhat accurate, and calculate a standard deviation for your value.propagated uncertainties, can anybody gimmie a definition in simpton english?
