What is the difference between precision and accuracy?
Precision: How close the results are to each other; Accuracy: How close the results are to the real value.

How can we determine to what accuracy our results should be left to are if we add or subtract?
Leave it to the lowest decimal place used.
2 of 6
How can we determine to what accuracy our results should be left to are if we multiply or divide?
Leave it to the lowest significant figure used.
3 of 6
How do we calculate the propagation errors for addition and subtraction?
The square root of the sum of squares of the absolute errors.

How do we calculate the propagation errors for multiplication and division?
The square root of the squares of the relative errors = the absolute error of the result / the result

Describe how to estimate
Put number into scientific notation, take the exponent on 10. If the first digit is 2-6 then add 0.5 to exponent e.g 3600=3.6*10^3~10^3.5. When converting back turn 0.5 into 3.
