**DrBob222**, Wednesday, February 22, 2012 at 6:11pmAnd you think the answer is what?

**Susan**, Wednesday, February 22, 2012 at 6:27pmWell i think the significant figures in the answer is 10, as the LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer. But I am not sure how to enter the actual equation into my calculator? So was hoping to see the answer and work backwards! :o)

**Susan**, Wednesday, February 22, 2012 at 6:40pmSo i start like this:

6.0223010000 x 10-24 x 2.222090001 x 10-30 (sorry not sure how to make the-24 and -30 small)

Then i do this:

(6.0223010000 x 2.222090001) x (10-24 x 10-30) =

13.38209483 x (10-24 x 10-30)

This is where i get kind of stuck!
