Example 3

easy
Subtract 8.03−2.578.03 - 2.57.

Solution

  1. 1
    Align decimal points. Hundredths: borrow to get 13−7=613 - 7 = 6. Tenths: 9−5=49 - 5 = 4 (after borrowing). Ones: 7−2=57 - 2 = 5.
  2. 2
    Result: 8.03−2.57=5.468.03 - 2.57 = 5.46.

Answer

5.465.46
Subtraction with decimals works like whole-number subtraction once the decimal points are aligned. Borrowing across the decimal point follows the same rules.
