First off, im VERY excited about this lol. Its sad i know, but its my life. I was getting tired of this long drawn out algebra problems associated with my engineering degree. So many mistakes, takes FOREVER. Not anymore :)

(My justification is we can use MATLAB to solve so why not this as well.)

The Algebrator

Solves everything out step by step if you want. Its awesome. So those long algebra problems that take 10 pages to finish (for those engineering applications) are no longer a nuisance. Also great for those in low levels math courses. I am SOO happy with this program. Hopefully i won't get shit from the teacher :biglaugh:. It has MANY functions including graphing and also does equation transformations (ie logarithmic). Also uses Cramer's rule :icon_bigg

Btw, for those interested, this is for reduction of an Equivalent Transfer Function (ETF); Automatic Controls 460 :3d_frown: :icon_evil terrible class in the sense its so hard/time consuming

input is very easy

I'm sure you can find an 'excellent' deal if you browse the internet enough :sarcasm: otherwise its 39.99


Either way, worth it in my opinion. This thing already saved me a few hours of labor.

When I was young sonny, we used to have to do math with no other tools but our head. But, let me tell you, I was quite the tool. It amazes me to see all the math classes today that allow calculators and such as this. My kids take calculators to school now. We would have been suspended if caught with one of those things. I recently went through an 8 week pre hire course for the new steel mill they are going to open sometime next year. They passed out our math final exam, and provided the calculator with it. Since the hiring depended on how well you did in classes, and your instructor's opinion of you, when I got mine, I turned the calculator face down while I had eye contact with him. I never touched it again, and finished faster than half of the class.

i call it resourcefulness


besides, at my level, algebra is already known well, but probably the biggest cause of mistakes in my field.

Precisely why you should still do it by hand. ;)














Haha, ok so that was my dad speaking through me.

Nice find! :)

I can understand basic algebra and such. However, again, at my level, there is some serious time and effort put into even the simplest problem. Typically 30min-1hr/problem, in other classes i've spent upwards of 2.5 hrs/problem. Most of the time is spent on basic algebra becuase there is so much of it. Because you're dealing with equations with over 50 parts each time its easy to get lost and screw up little bits which eventually turn to big things. This eases that problem big time.

I'd challenge nearly anyone to a basic algebra test and see who does it quicker and better than me and i would put money on i'd win 95% of the time if not more. But these problems just make you want to pull your hair out.
