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.
How To Add/Subtract DecimalsTo add decimals you HAVE TO LINE UP THE DECIMAL POINTS and then add the numbers up (Tip: when your first starting if the decimals don't go to the same place value you can add as may zeros at the END of the decimal. This does NOT change the place value)After you have added up the digits you "drop" the decimal point down.Example 105.43+23.4=?105.43+23.40-----------128.83To subtract decimals it's the same thing as adding YOU MUST LINE UP THE DECIMALS. You would subtract as you normally would.You would then "drop" down the decimal point.Example 109.783-43.39=?109.783-43.390----------66.393

This is true for adding and subtracting ALL numbers, not just decimal representations.
you dont they just like torturing you because in the past life you where Hitler
Line up the decimal points and then subtract one from the other.
Before the decimal 0.1, you have numbers from -0.1 to -0.9, which are negative numbers less than zero. In the decimal number system, the position to the left of the decimal point represents whole numbers, and as you move towards the left from 0.1, the numbers decrease in value.
