Project

Using the iterative and incremental style of project development, in your groups you will create a calculator

that can do the following $($for whole numbers only$)$:

$1.$ Add

$2.$ Subtract

$3.$ Multiply

$4.$ Divide $($integer division$)$

$5.$ Find the result of a $\%$ b

$6.($Bonus$)$ Find the GCD of a and b

$7.($Bonus$)$ Determine if a number is prime

The Catch

You may no longer:

$$ use $+,,,/,\%$ or any of the other standard Python operators.

$$ use any of the standard Python math functions $($e$.$g$.$ sqrt$())$

$$ use any numbers $($apart from $0)$

$$ use any logical or comparison operators $($apart from $==,$ and, or and not$)$
