Let's perform a simple computation involving both whole numbers and decimals. For example, we'll add a whole number and a decimal:

Operation:

$5 + 3.75$

Calculation:

1. Align the numbers:

     5.00
   + 3.75
   -------
   

2. Add the numbers:

   • $0 + 5 = 5$
   • $0 + 7 = 7$
   • $5 + 3 = 8$

Result:

$5 + 3.75 = 8.75$
