I am trying to have mathematica (Student Version 4.1) solve some algebraic equations that contain a margin of error for my physics lab reports. An example of what I am trying to do is add
((23.2+/-0.3) + (15.7+/-0.3))* 3.25+/-0.05 = ?
in which +/- means plus or minus. ( I didn't include the '= ?' in Mathematica).
I also want to be able to convert these margin of errors into percentage errors (as done when multiplying and deviding) and back.
I have found a way to use the 'PlusMinus' and 'MinusPlus' signs and tried to use them but the math didn't work out the way I expected it to.
