Group Like Terms: Step 1: Group the like terms and constants.1+10+f+7 can be grouped as (1+10+7)+f.Calculation: 1+10+7=18, so the expression becomes 18+f.
Combine Constants: Step 2: Combine the constants.From the previous step, we have 18+f.Since 18 is a constant and f is a variable, they cannot be combined further.
