Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. 1. Therefore you’ll improve your grades, as well as your math skills.

Write it out

You can also check a math problem by writing everything out on paper. 2. Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

3.

Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether your answer is the correct one.

Plug in（代入）

You may find that a variable isn’t good enough or have a problem where you have to solve for a variable (变量). 4. This is the only real way to assure yourself that the answer you’ve found is correct.

5.

If the result of a problem seems to make no sense, it indicates that the answer is incorrect. For example, if you get an answer in the millions and you know it should be in the thousands, you’ve likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you’ve got on the first try.

A. Do the opposite.

B. Correct the answers.

C. Plug the variable in the equation (方程) to check it out.

D. Knowing how to go through your math test and checking your work can save you from handing　　 in a test full of mistakes.

E. It also helps you to figure out everything after you have already finished the test.

F. Check for a reasonable answer

G. This helps you to know what information you have and what information you need to solve.
