PhotoMath , App which Solves Math Equations using your Smart Phones Camera

useless app, couldnt even solve a simple convolution between a rect function and an awgn

God, no offense but you sound like the kids back in my grade 10 class saying "what's the point of . I'm never going to need to solve quadratics in my life. Just use my graphing calculator for that." If math were to be applied to real life, all you would need is addition, and multiplication. 

Again same question. When in the hell would you need quadratics, and have NO ACCESS AT ALL to a calculator? Especially in this day and age? Other than a math class. We invent tools such as the calculator, so that we can use them and make things easier. I could apply the same logic to a fishing rod, we create it so that we can use it to make catching fish easier and not have to use our hands or a spear, although with that there actually could be a situation in which you need to catch a fish, and not have a fishing rod (a survival situation). But you don't need quadratics to stay alive.

 

Edit: And yes, I can think of several ways to catch a fish without a fishing rod, but the point still stands. Also, hypothetically if I was an employer, I would feel a hell of a lot better knowing my employee had used a calculator to get an answer, rather than doing it by hand as the margin of error for a calculator is much less

Sometimes you're given to demonstrate different stuff.

 

way to fight back nineshadow ! 

 

 

 

Somehow the app doesn't work that well for me

Too bad you cant use cell phones during tests.....

:(

Uh? Who said that?

[MeltingPoint]

If it can solve integrals, differential eqs, laplace and all that shit then i might give it a shot

The average Joe will likely never do anything more complex than basic fractions, percentages, and arithmetic. Having said that, maths has a huge range of applications in so many professional fields you simply cannot just brush it off.

Even if you're not going to go into one of those roles, it's necessary because it teaches analytical and logical thinking with some rather abstract concepts.

It also gives people who may want to go into those roles some exposure to the subject.

Oh I'm not against teaching it, I'm against the idea that it's better to do it long hand rather than using the calculator, that's all. I'd prefer just to know how to correctly get the right answer with a calculator as opposed to the excruciating process of doing things by hand (excruciating for me anyways).

 

I just see nothing wrong with teaching people how to get the correct answer with a calculator, as well as teaching them why the answer is what it is, I just see no advantage to doing things by hand when most of the time if you are doing something that would be more easily done on a calculator, chances are you are going to have a calculator.
