|
Significant figures
Multiplication Division |
calculations should not change the degree of uncertainty in a value.
When doing multiplication or division with the measured values, the answer should have no more significant figures then any number used in the calculation. |
|
|
Significant figures
Addition |
when doing addition or subtraction with measured values, the answer should have the same number of decimal places as the quantity with the fewest decimal places
|

|
Scientific notation
|
an exponent with a positive value tells you how many times to multiply a number by 10
an exponent with a negative value tells you how many time to divide a number b 10 |
