# why do we learn algebra in school

Do you love? Or are numbers the

Many professions, especially those in science and, require an extensive knowledge of. Even if you don't go into one of those fields, you'll probably use without even realizing it! Consider these examples: It's time to fill up your car's gas tank. The price of gas per gallon is \$3 and you only have \$25 to spend. How much gas can you purchase? This can be answered by the algebraic, 3x = 25. You must divide each side of the by 3 in order to isolate x. In this, x is equal to 25 divided by 3, which is 8. 33 gallons of gas. If you need 10 gallons of gas, how much money do you need? When you solve that, you have to thank! Or how about this example? You would like to purchase service for your home. Company A requires a setup fee of \$10 and charges a monthly fee of \$25. Company B does not charge a setup fee but charges \$26 per month. Which company is less expensive for one year of service? We can find out by first calculating the total cost for Company A: x = \$10 + \$25*12 (months in a year), which comes to \$310. The for Company B is x = \$26*12, which totals \$312. At first glance, it might have seemed like Company B would be cheaper, because they do not charge a setup fee, but showed us differently! There are many other examples of real-world uses of, from comparing prices on similar products in a grocery store, to figuring out what time you need to leave your house in order to meet a friend across town on time. If you ever WONDER something like, don't be afraid to ask your teacher or parent (or Wonderopolis! ). Odds are, there's a good reason! You should learn algebra, and master it, if you want to be successful; algebra is essential. WeБve all heard the mythologies for not having to learn algebra from bored high school students and the New York Times.

However, here is a look at a different set of myths concerning why you should learn algebra. You should study algebra because. math is inherently beautiful You should study algebra because. it will help you develop critical thinking skills You should study algebra because. youБll use it directly on the job It doesnБt take long to figure out that these myths arenБt fully satisfying. Most students will inquire as to the purpose of learning algebra and the vast majority of them will be given an answer that does not provide purpose and context but rather underscores to the student that even БweБ (the parents, the educators, etc. ) donБt know why we teach algebra. Math is beautiful said few high school students ever. IБm going to guess that the only people who say that math is beautiful are high school or college math teachers. Seriously, telling students that they should study algebra because itБs beautiful will only serve to further disillusion them with the very thing we want them to learn. Yes, math is beautiful but that isnБt why we should learn algebra. Critical thinking skills are a basic skillset that is developed in a variety of ways. Learning to read develops critical thinking skills. Reading challenging books develops critical thinking skills. Learning to БreadБ music and play an instrument develops critical thinking skills. Learning logic and rhetoric develops critical thinking skills. I think you are starting to get the picture. Learning algebra does have limited value in sharpening critical thinking skills but that is hardly a good enough answer to the studentБs question of Бwhy must I learn this? Б For the final myth, letБs be honest; how many of us actually use algebra directly on the job? IБve spoken with carpenters who regularly use trigonometry and many who only use basic arithmetic and are successful carpenters.
