In a previous post, I discussed the use of significant numbers. We know that when we perform calculations on a calculator, often, the number of digits we see on the screen is far more than we should report. And we now know how many to report, based on whether the computation involves multiplication, division, addiction, subtraction, or a combination of any of these.
When you report less digits than you see on the screen, you have to do some rounding. Rounding is a fairly simple concept and you should follow two rules when doing it. I will provide an explanation based on the Zumdahl and DeCoste text. I will discuss it with some examples.
