The process is the most important. I am also a math teacher. When my students revise their homework, I usually ask them to write the process. If there is only an answer, I will ask them to write the process again. Because only by writing out the process can I know if they will do it. Write out the process, even if the calculation is wrong, it means that the students will succeed, but there is something wrong with the calculation. Be careful next time, and you will do it right.
