1) Count to the digit you are going to round2) Look to the number to the right3) If the number to the right is below 5 you leave the digit
the same4) If the number to the right is higher than you round the digit up3) If the number to the right is 5…
And digit is even then keep it the sameAnd digit is odd then round it up to the next even
number4) If there are non-zero numbers after the 5 then round the
digit up5) Use zeroes as space fillers if they are needed.

1) Look to the numbers in the calculation2) Find the least accurate number3) Round answer to have same last
decimal place of the least accurate number.

1) Count number of sig figs in each number2) Make answer have same number of sig figs as the number with the least amount
1) Follow PEMDAS to solve-Use rules for add/sub and multiply/divide
when they applyP – ParenthesisE - Exponents and RootsM – MultiplicationD - Division A - AddingS – Subtracting
2) Make answer have the same amount of sig figs as the number with the least amount
Back
Sig figs are only needed when there is an uncertain digits like
when you are measuring. You are trying to make sure that your measurements are as accurate as possible. When you are counting there is no uncertainty.

To account for any error that occurs and make sure our measurements
are as accurate as possible.

Math – adding a point zero to a number doesn’t matter
-accuracy is less important in a number-If a 5 is next to the number you are looking
at the number rounds up-If a 4 or lower is next to the number you are
looking at the number stays the sameScience – adding more decimal places makes the number more accurate
-all about making accurate measurements and accounting for error
-zeroes count under certain rules -separate rules to round with 5’s

Adding/Subtracting involves rounding the answer to match the same decimal place as the least accurate number in a problem.
Dividing/Subtracting involves rounding the answer to match the number with the least amount of sig figs.
