AlgCalc is a free algebra calculator designed for Chrome browsers. It provides a basic algebra calculator that you can easily access from your browser. Developed by mrbubbles, this calculator aims to assist users in solving algebraic equations.

One of the standout features of AlgCalc is the IXL Autofill functionality. By pressing 'ctrl' + ' "', you can autofill the answers into IXL, making it convenient for students using the IXL platform. However, it's important to note that IXL Autofill currently does not support fractions in the problem, but the extension itself can still be used to solve these problems. Simply click on the extension icon, handwrite the problem, and get the solution by pressing enter.

AlgCalc supports various algebraic problems, including linear equations, quadratic equations (only for IXL Autofill), and systems of equations with 2 systems. The developer is actively working on adding support for more problem types in the future.

Please note that the latest update (version 1.4) may have introduced some bugs, particularly with the ability to add, subtract, multiply, and divide polynomials. Additionally, the solve button for IXL is now available on the extension popup, but still requires manual selection of the problem.

Overall, AlgCalc is a useful algebra calculator for Chrome that provides convenient features for students using the IXL platform.
