More sophisticated calculator

Ask the user for their 1st name

ask the user to enter two numbers

then ask the user to select what operation they would like for you to do (+ - / X) [add, subtract, divide or multiply]

then do the operation indicated.

providing feedback for the user with the answer.

​

do this 5 times (going back to the start and asking the user for a new set of numbers and a new operation to be solved).

clearing the screen in between each new operation.

​

Have fun coding! 😃
