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?

  1. The units digit is not significant (the zero in 150)

    150+80+210=440

    How can calculations affect the accuracy and precision of experimental results? Calculations, such as division and addition, can decrease precision in data by generating more digits that can be significant. Nonzero digits are
