Definition: Adding decimals, Write the decimals so that the decimal points line up vertically. Add as with whole numbers. Place the decimal point in the sum so that it lines up vertically with the decimal points in the problem. Subtracting decimals, Write the decimals so that the decimal points line up vertically. Subtract as with whole numbers. Place the decimal point in the difference so that it lines up vertically with the decimal points in the problem. Calculation: \(\displaystyle{200.49}+{16.82}+{103.002}\) 200.49 and 103.002 has 3 whole value. 16.82 has 2 whole value. So, add 0 to 16.82 at the front. The number becomes 016.82 103.002 has 3 decimal places. 16.82 and 200.49 has 2 decimal places So, add 0 to 16.82 and 200.49 at the end. The number becomes 016.820 and 200.490 Based on the definition, \(\displaystyle{200.49}+{16.82}+{103.002}={320.312}\) Answer: \(\displaystyle{200.49}+{16.82}+{103.002}={320.312}\)
