Asked by Brandon
                I am supposed to add up these numbers, using the significant digits rules.
150
76.9
209
.036
I got 435.936. Following the sig. digs. rules, it would be 435.9, right? How does this then equal 440 as my science books says? Thank you so much.

    The lowest sig fig in all the number you added was 2. So you should round your total which is 435.936 so you can get 2 sig figs in your answer. 440 has 2 sig figs.

    Chopsticks is almost right. The least sig digit is the tens (150) so nothing past that makes any sense.
440
