Session 6: Calculator

Session 6: Calculator#

Project description#

In this project we have to implement a simple calculator that supports these for operations:

+: add
-: substract
*: multiply
/: divide

Also we want to have history. We want 10 history rows and we should be able to switch between history rows using up and down keys. For more detail see the examples.

We also need a button that deletes a history row.

No need to supprot float numbers.
You are free to come up with your own different keys, these key combinations are just for an example.
You can add any number of keys that you want.
Only need to support and operation between two numbers.
