I dont know the answer but I've been trying to look up some famous mathematician and its just giving me people who invented science stuff.
sorry for the trouble...
but if your reading this here is a great passage:"the path of glory leads but not to death"When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.
Subtracting a fraction is the same as adding its negative.
adding
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
Three significant figures: two before the decimal point and one after.
When adding or subtracting measurements, the number of significant figures in the result should match the measurement with the least number of decimal places.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.
When multiplying or dividing numbers, the result should have the same number of significant figures as the factor with the fewest significant figures. When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places.
When adding or subtracting measurements, the result should have the same number of decimal places as the measurement with the fewest decimal places. When multiplying or dividing measurements, the result should have the same number of significant figures as the measurement with the fewest significant figures.
Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places
When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places. When multiplying or dividing numbers, the result should have the same number of significant figures as the number with the fewest significant figures.
The sum of 5.1 and 3.2 is 8.9 with two significant figures. When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places, which in this case is 3.2.
When adding numbers with different significant figures, round the final answer to match the least number of decimal places in the original numbers.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
