Today we learned about significant figures which tell how precise a measurement is. The significant figures are any non zero digits and all zeros in between. Don't count the zeros before the first non zero digit but do count the zeros after the last non zero. Those are called trailing zeros. When multiplying and dividing, the product or quotient must have the same number of sig figs as the factor which has the least number of sig figs. When adding or subtracting the answer must have the fewest digits after the decimal as least precise number.
Practice problems:
Determine the number of sig figs
1. 6.002- 4
2. 0.0020- 2
3. 10.0500- 6
4. 52.13+1.7502
That equals 53.8802 do the answer is 53.88
Hey. So I got all the same answers you did... Either we're both awesome and did it right or we both messed up. I think we did it right though. By the way, Thanks for helping me with the homework today, I understand it now for the most part. :)
