Assignment: 02-Add and Subtract Decimals
Adding and subtracting decimals is no different than adding and subtracting any multi-digit number. The key thing to remember is you have to line up the decimal points. From there, you just add from right to left, being sure to carry when needed. Remember, the decimal point in the answer is included in the aligning of the decimals.
Subtraction looks the exact same, except for rather than carrying the ones, you might have to borrow from the previous column. also shown in the subtraction problem, is what you would do with a whole number. When the decimal point is not shown in a whole number, it is assumed to come just behind the ones place. 33 = 33.0 Remember, we can add as many zeroes as necessary to the end of number to make a problem possible.
