シンプル電卓：式が見やすい計算機

The app's greatest feature is its "Easy-to-Read Formula Display," which displays formulas as they are calculated on two lines.

For example, when calculating "100 + 50," the display will show "100 + 50."

This makes it easy to see what calculation is currently being performed.

Furthermore, the answer is displayed as you type, so you can see the formula and its result at a glance.

This clarity prevents miskeying and calculation errors, making daily calculations easier.
