Bugs to correct:

Features to add :

1. Keyboard support.
2. Be able to input negative numbers.
3. Responsiveness.(partially added[now margins don't change when zooming in or out])
4. When a user inputs two numbers, the operator buttons can perform as the equals button.

Added features :

1. Backspace button.
2. Restrict division by zero.

Corrected bugs:

1. When you press an operator button twice, this makes the calculator behave in a non expected manner.
2. Excesive amount of decimal numbers shown on screen that overboarded the calculator screen.
