**__ HOW TO ADD AND SUBTRACT DECIMALS. __**
__**Lesson 1:Adding Decimals **__ Find the sum of 14.7+3.2 First, estimate the sum :15+3=18 Next, line up the decimal points : 14.7 __+ 3.2__ 17.9 Compare the answer to the estimate:since 17.9 is close to 18, the answer is reasonable. __**Lesson 2:Subtracting Decimals **__ Find the difference between 3.876 - 2.173 First, estimate the difference   :4.000-2.000=2.000 Next, line up the decimal points : 3.876 __-2.173__ 1.703 Compare the answer to the estimate: since 1.703 is close to 2.000, the answer is reasonable. **Links:** **[|ADDING AND SUBTRACTING DECIMALS]**
