The Math AI, Step-by-Step Auto-Grading engine checks each working step and provides instant feedback on Algebraic Manipulative types of questions. Students can input the expressions or equations using the keyboard or the handwriting recognition feature. It can auto-grade the following topics: Simplification, Expansion, Factorisation of Algebraic Expressions Solving Linear, Quadratic Equations and Inequalities If a grey cross appears, it means the step is incorrect and the student has to check back to correct the working method or step. If an orange tick appears, it shows that it is an intermediate working step. So, the student has to continue to present working steps for checking until he or she obtains a green tick. The engine allows students to explore different methods and full solution is provided too. With the app, mastering the skills on solving algebraic questions is easier.
