Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. ___16___ 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. ___17___ Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.
___18___
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). ___19___ This is the only real way to assure yourself that the answer you’ve found is correct.
___20___
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.
