Everybody has their different ways of solving math. Some count their fingers, others use calculators, and some people can even do it all in their head! Here are some ways of how I solve math.
For me, it depends on the problem. If the problem is big, then I show my work. However, if the problem is small or basic, then I can do it in my head. For example, 39,874x234 is a big problem, but 6x9 is basic. You should know right away that 6x9 is 54, since you learned it ever since 3rd grade. However, you can't just do 39,874x234 in your head, and even if you did, your mind will feel jumbled and get it wrong. Unless your a super smart person like Albert Einsten. Most equations like variables include doing your work. For example 3n-5=21. It's possible that you can do it in your head, but a better idea is to show/do your work.
