A methodology for character recognition and revision of the linear equations solving procedure

作者：

Highlights：

• We present a method to segment individual equations in a solving procedure.

• We propose comparison rules to revise a set of consecutive linear equations.

• We automatically review the procedure for solving one unknown linear equation.

• We revised the linear equation solving procedure with an efficiency of 86.66%.
