This was sent back. It is a chemistry sig problem in freshman chemistry Why is 1376 - (2.4x102)= to 1140 and Not 1136 when using sig figs. I thought subtraction went to the closest decimal. 1376 - 240 1136 Is there a different rule when using exponents. The 4 was the last sig fig in that problem. Should I really be looking at the last sig fig when adding and subtracting. Thank you

When you are doing addition and subtraction, my chemistry text tells me to round to the least number of decimal places. It also tells me when rounding to use the rule that if its 5 or more, to round up.I have a problem that tells me to solve 0.881+132.1-12.02. The full answer I get is 120.961.Since I need at least one decimal place, should I keep it as 120.9 or round up to 121.0?
