I am calculating the percentage of error again, and the expression is 2.76-.7/.7, I got 2.94. Should I move the decimal over so it's 29.4?
I have to find the percentage of error. The accepted value is 11.35, while the value I got is 2.564. I got 2.564-11.35/11.35, and got a negative answer. Can percentages of error be negative? Thanks-Coralie.

We are currently studying significant digits/figures. I was asked to add 150 ml with 76.9 ml, plus 209 ml plus 0.036 ml. The book says the answer is 440, but I got 435. (the complete answer, without applying the significant digits rule is 435.936) How did I do this incorrectly?
I can see why that'd be so hard to write, because either way wouldn't be the best ending. Maybe she could choose the crush, but she would accidentally find out from some gossipy girl that it was the friend who set them up, the friend who really loves her. That way you ...
