Understanding Decimal Addition and Subtraction
Decimal addition and subtraction are fundamental arithmetic operations used to combine or find the difference between decimal numbers. Decimals are numbers that include a decimal point, representing fractions of a whole number.
Key Concepts:
- Place Value: Understanding place value (tenths, hundredths, etc.) is crucial. Align decimal points when adding or subtracting.
- Addition: Combine decimal numbers by adding digits in corresponding place values, carrying over when necessary.
- Subtraction: Find the difference between two decimal numbers by subtracting digits in corresponding place values, borrowing when necessary.
- Combined Operations: Perform a sequence of additions and subtractions from left to right.
Example: To calculate 5.7 + 2.3 - 1.5, first add 5.7 and 2.3 to get 8.0, then subtract 1.5 from 8.0 to get 6.5. This calculator simplifies these operations, providing quick and accurate results for combined decimal addition and subtraction.
