Percent Error, Scientific Notation, and Significant Figures
Percent error is a way to check a value and compare it to another value
Scientific Notation is another way to out large decimals into smaller numbers. By typing in your calculator "EE" or "Exp" and replace x10 you will able to find a smaller and significant number.
Some rules to scientific notation is
the coefficient MUST be between 1 and 10
take that number and times it by 10
the exponent will determine the place value of the decimal
for the signs on the exponent if the number is 0 and 1 it will be negative and if it is a number greater than 1 it will be positive

Depending on your instructor, sig figs or s.f will be a huge lesson to learn because some instructor will count answers wrong if your significant figures are off.
To know how many sig figs you use here are some rules to help you:
1. Any digits not including 0 are significant and have 3 s.f2. Leading zeros (zeros to the left) are not significant and have 1 s.f
3. Zeros in the middle that are surrounded are significant and have 4 s.f
4. Trading zeros (zeros at the end) are significant if the number contains a decimal point which can contain 4 or 3 s.f
