Second, many shortcuts are applicable only to specific situations, so before using a shortcut, make sure that it is relevant to the problem at hand.
(4) Memorize arithmetic computations that deserve memorization.
Usually, once you get the math equation, you're fine; the actual math involved is often fairly simple.
But figuring out the actual equation can seem nearly impossible. Be advised, however: To learn "how to do" word problems, you will need to practice, practice, practice.
Here are five effective means to do so: (1) Read the question.
In any Math problem, there is a paramount need to read the question carefully, from beginning to end, so that the student can take down all given facts and keep sight at the unknown.Knowing all of these before beginning to solve will help your solving run on a smoother path. After reading the question you should be able to translate all the given data into mathematical equations.Also, keep in mind to select proper notation for your equations. Any formula or procedure that could shorten the solution is a shortcut.One of the most common complaints of students during Mathematics examinations is that they often run out of time; in that case, advice on how to solve math problems more quickly will help them finish timed exams.Math is a complicated discipline, and while some problems are routine and straightforward, some problems require zigzag mazes and long expositions of solutions before an answer can be found.These include: powers of bases 2, 3, 4, 5, and 6 (up to the 5th power, at least); multiplication tricks (multiplying by 11, or multiplying numbers with zeroes in the end); and some subtraction tricks (like 10000 - 443 = 9999 - 442).There are plenty of tricks available; if you practice them at your spare time, then you have an edge in speed and agility over your peers. Simplifying fractions into lowest terms and rationalizing radical expressions can make your numbers on paper more organized and easier to handle arithmetically. Well, it's going to be w plus w plus 2w plus 2w. The perimeter of this garden is going to be equal to w plus 2w plus w plus 2w, which is equal to what? But they also tell us that the actual numerical value of the perimeter is 60 feet. So this perimeter 6w must be equal to 60 if we assume that we're dealing with feet. We can divide both sides of this equation by 6 so that we have just a w on the left-hand side. Many teachers, while willing to give plenty of help to their students so that they can be faster in Math, do not have the time to do so.In that case, it is up to the student to figure out techniques on how to solve math problems more quickly than they did before.
