DailyUI#004 - Calculator

PROBLEM :
From my own experience using the default iPhone calculator and from discussions with several friends, I identified two major pain points -
1. many times we need to do calculation among multiple numbers, and we have to keep notes of previous results ourselves so that we can use them later to do another calculation.
2. sometimes during complex calculations that involve multiple numbers, there lacks a way to quickly sanity check if the result is actually from the numbers we entered.

SOLUTION :
- I utilized the space directly under the result to visualize calculation the user have just entered.
- I also introduced a history section that contains the most recent five results, so users can easily recall their previously calculated numbers. More information on the interaction to come!
