lessons if you need a little help!
Adding decimals

Step2) Add normally as if there were no decimal

Subtracting Decimals

Step 2) Add zeros (if needed) so the numbers are the same length
Step 3) Subtract normally as if there is no decimal
Step 4) Bring down the decimal
Multiplying Decimals
Step 1) line up the numbers
Step 2) multipy as if there is no decimal
Step 3) Place the decimal in your product by starting at on the right and moving to the left the a number of places equal to the sum of the decimal places in both of the numbers being multiplyed
Dividing Decimals
Decimal only in Dividend
Step 1) divide ignoring the decimal point
Step 2) Bring the decimal straight up
Decimal in Divisor or Both
Step 1) shift the decimal point to the right of all of the numbers to make it a whole number, but what you do to one side you have to do to the other so you move the decimal point an equivalent amount of times as you did the divisor to the dividend.
Step 2) Divide normally or follow the steps above
