How to Solve Any Math Problem in Four Simple Steps

Math can be a very polarizing subject. Some people love it (generally because there’s always one “right” answer)and other people hate it (generally because there are so many formulas to remember). No matter which category you fall underchances are that you’ve encountered a math problem that seems impossible to solve. Thankfullydue to the nature of mathematicsthere are no unsolvable problems — only ones to which the solution is not immediately clear.

Step 1: Be sure you understand the problem.

Before attempting to solve any math problemit’s essential that you understand what the question is asking. First read through the entire problemwithout writing anything down. Nextre-read the problemthis time determining what information the problem provides and what information it’s asking you to provide. Organize the information obtained so that it makes sense to you. This organization may be a tablea listor a sketch. There are no “wrong” methods of organization when it comes to math.

Step 2: Come up with a plan.

Now that you have all your information organizedit’s time to come up with a plan. Have you done problems like this one before? If it’s not clearfind a way to simplify the problem. Sometimesthis is as simple as reducing fractionspulling out factorsor estimating. Other timesthis may require writing the problem algebraically and then solving it with smaller numbers first. If it seems impossible to pull a simpler problem out of the problemyour best plan may be an educated guess — but be aware that guessing tends to be harder to check.

Step 3: Work through your plan.

Once you’ve come up with a plan and an equation to solveit’s time to solve it. Math is formulaicso if a problem looks similar to another problem you’ve done beforethere’s a good chance that the system used to solve it is the same. Consider all the math concepts you have learned so farand be sure that you’ve applied the relevant ones to your examination of the problem.

Step 4: Check your answer.

After you’ve done the work of solving the problemit’s time to double-check. Does your answer make sense for the way the problem is worded? If it isn’t reasonable for the answerrevisit the steps of the problem to see where you went wrong. It could be that you used the wrong methods for solvingor it could be a simple arithmetic error. If possiblecheck the answer in the original problem itself. Does it fit? Adding the answer into the original problem may uncover an easier way to solve this type of problemwhich will help you the next time you encounter one.

While not everyone thinks mathematicallyeveryone can learn to be an excellent mathematician. Math is all about pieces: If you learn what those pieces are and how they work togetheryou can solve any math problem — every timeand if you’re having a hard timejust use our calculator above to figure it out for you.
