TermDefinition
Adding DecimalsLine up the decimal points and add normally (ex. 23.62+8.369=31.989)
Subtracting DecimalsLine up the decimal points and subtract normally (ex. 20.02-1.36=18.66)
Multipling DecimalsIgnore the decimals and multiply normally. At the end, put the decimal back in according to its place value (ex. 9.65 and 5.1 would be moved in 3 places because you count in from the right)
Dividing Decimals by DecimalsMove the decimal in the number outside the box over as many places as you need to to make it a whole number. Then do the same with the number inside the box. If the 2nd number still has a decimal, bring it up and divide normally
Finding PercentsMultiply the number you want to find a percent of by a percent in decimal form (ex. 56% would be .56 and 3.4% would be .034 because you always move the decimal over two places)
Finding Sales TaxMultiply the amount of money by 1.whatever the sales tax is (ex.for a sales tax of 6%, you multiply the price by 1.06)
