RootCalcA is an Android calculator application that performs calculations for expressions containing square roots (represented by the symbol "√"). The app simplifies expressions within the square root, expands the expression, and rationalizes the denominator for fractional expressions.

The results are presented in a form that includes square roots or fractions, as required. However, decimal values are not shown.

Note that if the denominator is complex, the numerator may exceed the display frame or the result may be incorrectly displayed. In some cases, the app may also terminate abnormally due to a stack overflow. The use of fractions within square roots is not supported; instead, please use square roots for both the numerator and denominator separately.
