Your prefix is $520.$ Multiply this by $500,$ and the result is: $260000$

Add $10$ to that result and multiply it by $60,$ and the result is: $15600600$

Your line number is $2600.$ Add this to the previous result three times, and the result is: $15608400$

Subtract $600$ from that result and divide it by $3,$ and the result is: $5202600$

n$.$b$.,$ In order to process a phone number $($e$.$g$.,5202600)$ into prefix $(520)$ and line number $(2600),$

you will need to use the floor division $($i$.$e$.,\text{'}//\text{'})$ and modulo $($i$.$e$.,\text{'}\%\text{'})$ operators. Consider

trying the following exercise $($with Python running in interactive mode$)$ to help you

accomplish this:

What is the result of the expression $123456//100?$

What is the result of the expression $123456\%100?$

What happens when you change the second operand $($i$.$e$.,$ the $100)$ in the expressions?
