When I was teaching, I ran into a serous problems regarding calculators. They rob the student’s brains of the ability to conceptualize math. They can’t see 1+1=2. The problem was, they could not do even the simplest of equations. An equation such as x+1=2, Solve for x. Tried every way including a variety of physical representations. Example: Put a box down then a large plus sign on paper, then a pencil. Next a large equal sign. Finally 2 pencils. Question, how many more pencils would have to be in the box, if I combined them with the pencil showing on the left to equal the two pencils on the right. Blank stares all around.
Now, why should algebra matter, right? Well it matters a lot more than you realize. Ever go into a store to purchase a coke? You used algebra. In your mind, you used an equation, hardly without thinking. The equation, do I have enough money in my pocket to buy the coke. The equation, will the amount of money spent on the coke exceed the amount of money I have? Or current cash - Money to purchase coke => than 0.
We make these determinations every day in our lives. Or at least we should.
Now far too many of us avoid this by using a credit card(s) and running up a massive debt. They keep using new second mortgages or bill consolidated loans until the magic day comes up in court where the Judge relives them of their debt in exchange for now useless credit cards. And as usual. You and I, who have our finances in check, live as close to or above our means as possible, pay the bill because the merchants and other creditors have to charge more to make up for the losses. Credit is not free, but Algebra pays.
Final thought, once while eating lunch, many years ago, we overheard a fellow complaining about his bankruptcy settlement’s requirements. We overheard because he was complaining so loudly it was pretty much impossible to ignore. Oh, all the classes he had to attend, all the things he had to give up. it was such an “injustice” to him. What an ass.
