5. MASTER THE ACTION THAT “LET … AS X.”

The difference between Math and arithmetic in primary school is using letters like “x” , “a” or “f(x)”. So, you have to master the action that “Let … as x.” I feel this is very important method everyday. Because I also use this at solving math everyday. Specifically, if you are asked in the last of a question “Find the value of … “, you can start your answer as “Let … as x.” You can start a story of solving with this action.

This is very effective. Because if you master this action, your score will go up. I think so. Don’t forget.

See you next.
