and has following features.
- Fractional expression with missing number is also acceptable.
- Font size adjustment according to the length of expression.
(Large font size for short expression and small font size for long expression.)
- Other User Interface Improvement for iOS7.
(This app is designed for both iPhone and iPad, and only for iOS7.)
The operation flow is similar with current apps.
(1) Normal Fractional calculation
The initial stage is as follows. We can always jump to this stage by touching "Reset".
Then we will proceed with expression input process by touching numbers and operational pads.
We can enter fraction input mode by touching "b/a" or "c b/a" as follows.
Once the fractional expression input complete, touch "Go" to start calculation mode as follows.
The following is one of the calculation scene. Step by step calculation is easy to understand.
The following is the scene when calculation is over.
At this time, you can go backward and confirm previous calculation precess again
by touching upwards arrow.
Touch "Reset" to start another calculation.
(2) Calculation with a missing number.
Following is one example.
(You can specify missing number only once, and only in the left side of an expression.)
By repeating 'Go', you can get the following result.
(3) Font size adjustment
Following is one example.
Small font size is used for long expression, on the other hand large font size is used for short
expression.
