Adding decimal same as adding whole numbers
When you are adding and subtracting decimals, youare +/- ing the whole numbers and tenths in the number. the decimal might go away ex: 1.3-0.3=1 or it won't ex: 1.9-0.3=1.6
When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.
First you write the decimals one under the other, in such as way that the decimal points are aligned.
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
Yes, unless you are an expert.
Write them one above the other with the decimal points aligned.
Yes, When Adding and Subtracting decimals you should line up the decimals. You need to keep each place value in the same column, the same as when you add whole numbers you keep the ones column lined up, same for the tens, etc. Lining up the decimal points makes sure that the tenths column is kept together, same for the hundredths, and so on.
This is effectively the same as lining up the decimal points when adding or subtracting ordinary decimal fractions.
you only line the decimals up when you are subtracting or adding not when you are multiplying im not sure about division...
It can be same because it,s just the decimal
