Homework Help: Chemistry

Posted by Brandon on Thursday, February 19, 2009 at 5:05pm.

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.
