To solve (10.005 - 0.5):

Step 1: Align the decimal points

Rewrite the numbers with aligned decimals (add trailing zeros to make them have the same number of decimal places):
(10.005 - 0.500)

Step 2: Subtract digit by digit

• Thousandths place: (5 - 0 = 5)
• Hundredths place: (0 - 0 = 0)
• Tenths place: (0 - 5) → Borrow 1 from the units place (units place becomes 9, tenths place becomes 10). (10 - 5 = 5)
• Units place: (9 - 0 = 9)
• Tens place: (0) (since we borrowed earlier)

Result

(10.005 - 0.5 = 9.505)

Answer: (\boxed{9.505})
