Remember
- Line up the decimal points so tenths are over tenths and hundredths are over hundredths.
- Write placeholder zeros so both numbers have the same number of decimal places.
- Regroup in decimals the same way you regroup whole numbers.
- Estimate by rounding to the nearest whole number to check the answer.
- Use the opposite operation to check: add the difference back to the subtracted number.
