Green Calc

"In a Galaxy far, far away on a planet called Sam lives a species called Sung that is very different from humans. They only have 3 fingers instead of 5. As a result, they use different numerical system than inhabitants of planet Earth. Sungs only recognize shades of green and are very keen on seeing your solution for a base 6 calculator implemented using React Native technology."

Breakdown

1. "They only have 3 fingers instead of 5"
2. "only recognize shades of green"
3. "base 6 calculator"

Analysis:

1. Assumption: The user has 3 literal fingers, so no thumb.
2. Assumption: All colors used must be some recongnizable shade of green.
3. Assumption: Numbers are entered in base6 and always viewed in base6.

In order to combine my assumptions and the requirements, I'm going to do this in the following way:

• All colors will be shades of green
• Numbers will appear only in heximal form
• I'll assume the user holds their three fingers over the screen and presses all the buttons in the left column with left finger, middle column - middle finger, and right column - right finger
• It works with fractions
• It will handle negative Numbers
• Will handle order of operations, left to right BEDMAS
• If you divide by 0, the result is Infinity

To Use:

1. npm install
2. react-native run-ios or react-native run-android

To Test:

1. npm run test
