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
