Significant Figures and Rounding Numbers cont.

Rounding is a process to estimate a number in a calculation or reading to a specific

place value.

To round a number, look at the next digit to the right of the place value in question.

If the digit is less than 5, round down to the current place value; if the digit is 5 or

greater, then round up one number in that place value.
