16 views2 pages
Document Summary
3. 83 x 10^3 (when rounding, you must reduce as well) 0. 500 (here instead of taking away digits, you have to add in order to meet the amount of sf) Add and subtracting - the answer is limited to the number of decimal places as the number that has the fewest decimal places. Example: 0. 250 + 0. 250 = 0. 500: if you have 3 sf after the decimal than your answer has to have 3 sf after the decimal as well. Multiplication and division - the answer is limited to the number of significant figures as the digit with the fewest significant figures. 8. 24 x 10^3 1. 1 x 10^-4: exact numbers. Determine by counting and not by using a measure device. Assume to have an infinite number of sf. Examples: 1 inch = 2. 54 cm (exactly, 9 pencils (exactly : obtained by counting.
