Calculator

React assignment

Question Description

Create a basic calculator using react. Your app should have below mentioned functionality.

• Add
• Subtract
• Multiply
• Divide

Tasks:

1. Present all digits(0 to 9) and five symbols (*, %, +, -, =) and a display area (No need to write fancy css).

2. Allow all four operations to happen. User should be able to use last result with a variable "_" (underscore).

3. Allow user to use both keyboard and onscreen fields.

4. For simplicity you can clear the screen once user presses a symbol.

Eg:

• User presses 1123 (Display area shows 1123)

• User presses * (Display area now only shows *)

• User presses 0 (Display area now only shows 0)

• User presses enter or = symbol (Display area now shows 0)

• This complete one cycle.

• In the next cycle user selects _ + 3 (Display area should now show 3)

• In the next cycle user selects _ * 4 (Display area should now show 12)

• Note: User need not focus on the display for the calculator to work. Eveything should work even without touching the mouse.
