FracExpressionA: A Fraction Calculator with Variables and Factorization
FracExpressionA is a free Android app developed by Haesaka, which serves as a calculator for fractional expressions containing up to three variables. The available variables are x, y, z (or a, b, c), and parentheses can be used to group terms, with input up to fourth power. The results are displayed primarily in factored form, except for expressions containing variable terms of sixth power or higher, which are displayed in expanded form.
The app allows input of complex fractions within the input frame, and can also function as a factoring calculator for simple polynomials. Users can also input numerical values, which will be calculated as fractions instead of decimals. This app can handle most fractional expressions that appear in high school math textbooks and problem sets.
However, it is important to note that the app may not display results correctly for expressions containing variable terms of 17th power or higher, and may also produce incorrect results for complex expressions due to overflow issues in 64-bit integer calculations. This app is suitable for users who need a fraction calculator with variable support and basic factoring capabilities. For users who require polynomial expansion, FactorizationA or FactorizationSA may be more appropriate.
