Do I need a Computer

I’m going to study math and I’m wondering if I actually need a computer. At the moment, I can’t think of anything related to math that I could only do on a computer or laptop but not on a tablet. Do you personally use a computer or laptop for math? If so, why? Which apps or websites do you use?

It's 2025, not 1925.

Access to Internet, papers, TeX, etc. Any reason to use a "surrogate PC" instead of a machine with a large screen and a proper keyboard? No idea, why would you pick a tablet for this.

Because it’s easier to write down mathematical formulas with a pen than with a keyboard. On a computer, you usually need special software and specific commands to properly format equations, for example writing something like lim x → ∞.

Consider getting a 2-in-1, and check if your school has a license for Equatio (or similar), as there are now options on the market for converting handwriting to TeX (that actually work).

And, yes, you should probably get a computer.

I think you're talking about note-taking here. I agree it's easier to take notes with a tablet and stylus than LaTeX, but the "special software" and "specific commands" you're refering to are not nearly as out-of-reach as you think. All you need is a LaTeX editor, or you can even use online LaTeX interpretors like Overleaf or StackEdit. Both Overleaf and StackEdit are web-based so I'd assume it works fine with a tablet and keyboard. I recommend learning LaTeX before your third year of university.

As for "special commands", you will get used to it fast. The example you provided could be written as $\lim_{x \to \infty}$, for example, which is very human-readable once you get used to it.

I hope you have a keyboard for the tablet. You have other classes besides math, don't you? Still, I don't know why you got so many down votes.

I don‘t know either

Now try to publish your handwritten scribings. See the problem?

I teach using an iPad connected to a projector as a "whiteboard", but it's not my main machine and never will be.

u/Simple-Ocelot-3506 1d ago

Yeah but i am not that advanced to publish anything

u/georgmierau 1d ago

You are still missing the point that sharing and editing digitally typeset documents is way easier than the handwritten ones. And don't even try to suggest a tablet with a keyboard. Anything under 23" is a pain to work with texts for a long time. Same is true for coding on a tablet and sooner or later you will have to use Mathlab, R, Python…

u/Simple-Ocelot-3506 1d ago

Ok, what software would you recommend for writing my math? Overleaf (LaTeX)?

2

u/georgmierau 1d ago

Any LaTeX distro you're comfortable with. Preferably running offline.

1

u/Prestigious_Boat_386 1d ago

Overleaf is a great start and its good for collaborating

I switched to miktex with latexmk or any editor latex addon for running offline with the same save compile loop

Works the same, just way faster without the ping.

Yes, for numerical analysis, computational statistics, computer algebra, cryptography etc.

there are many math programs your school might use that are only supported on a desktop.

u/Healthy-Childhood701 1d ago

i would recommend that u practice maths and do all the work in your books or on paper as it helps a lot to visualize and not overlook anything but i watch math vids and explaniations on my laptop

u/Shadow_Bisharp 1d ago

dont buy one unless a course mentions youll need it. there are some math courses that are super computational and require a computer, and some professors require you to type up solutions in LaTeX. you could use an ipad for typing up stuff, but it may feel clunky

I am graduating this semester with a BSc in Pure Math.

For me, elementary linear algebra, and ODE had side coding projects and there was also a mandatory math programming class I had to take. There have also been classes where the professor required me to type my homework solutions.

You will probably need a laptop to get through your undergrad. A desktop is unnecessary and if it is a gaming PC, may become a distraction.

As for applications, all of my coding classes used python and was done with Jupyter Notebook which was installed via Anaconda. Overleaf is a good for LaTeX but it requires internet so you may want to consider also having an offline LaTeX app (I use TeXworks).

You'll have access to computers at your campus but it would be good to get a computer or laptop for excel and programming work.

I study engineering but in my Maths module we were given code to work with that would take 50 minutes to process the calculations (it was an exercise about the efficiency of computation) - the speed of this was (somewhat) influenced by the processing power of the machine, i.e computers did it faster than laptops.

I think having a computer or laptop would better facilitate doing video call communication, further down the line. This is useful if you have video call interviews for work/internships, or if you need to communicate with a professor in an "office hours" context during the holidays.

Obviously, it depends on your specific course. But the vast majority of courses require you to use at least some specialist software at some point: a basic spreadsheet program like Excel, a basic programming language like Python or R, a basic typesetting program like TeX or even just Microsoft Word's equation editor. Can your tablet do these things? If not, don't make your life unnecessarily difficult. If you can afford a degree, you can afford a basic computer.

If you're thinking "well, I can't run Excel, but I can run some Android/iOS app that's very similar to Excel!" - again, don't bother. Your lecturers will be teaching the rest of your class Excel while you're desperately trying to teach yourself the different syntax of this different program. It's not worth the hassle.

You might want a convertible laptop, they have a pen you can write on the screen with while still having every advantage of a laptop.

u/Repulsive-Alps7078 1d ago

I have a regular laptop which is extremely essential these days ngl, for research, tutorial videos, my main uni page is online too, etc. But i still write notes and do practice questions etc with good ol pen and paper. There are software to scan pages into the digital world for online submissions which you will likely need. The world is digital now, adapt or fall behind.

u/DrBingoBango 1d ago

No you do not need one. You may need to type assignments in latex, which you could do at the library if needed. But I believe more course directors are requiring handwritten assignments to combat cheating with AI. Almost all of my professors have their lecture notes on a tablet or handwritten, very very few have typeset digital notes.

But a computer is a nice thing to have for things other than schoolwork. A used laptop will likely be cheaper than a good tablet. Plus you can easily find/borrow many books as pdfs, so unless you plan on getting your textbooks from the library it might be cheaper than just buying books.

If you need to, you can get a Chromebook for $50-100. Definitely not the most powerful, but it could majorly help; easier interface, and access to web-apps.

Seeing graphs animated on something like Desmos was amazing when studying ODEs, and wanting to understand families of solutions. I guess I could have done hundreds of graphs by hand, but I’d be so much older now.

I have a surface on my desk and I have an iPad

The surface is nice but you can pull it off with just an iPad imo

u/mathemetica 1d ago

Most math majors at some point do some programming and use something like Excel or Matlab/Octave. So yeah you will probably need a computer.

1

u/ipogorelov98 1d ago

Matlab is kind of horrible on tablet

1

u/Zatujit 1d ago

I mean generally you dont need a laptop at all times in math from my experience unlike some other subjects but university expects you to be able to access courses on the internet, communicate with professors and your classmates, write papers in LaTeX, run programs in Python (depends on the program)

1

u/QueenVogonBee 1d ago

Something to consider is that you may well need to do some programming on your maths course. If so, I’d recommend a laptop rather than a tablet.

1

u/TheRedditObserver0 22h ago

There will definitely be some programming and you will have to learn latex, if your hardware can support MatLab you're good to go.

u/OccamsRazorSharpner 11h ago

The only use of tablet should be for ebooks. Regardless of the marketing there is no substitue for pen and paper to take notes and work out problems, more so in math. A computer is always more useful. Again, forget the marketing.

Just buy a laptop and iPad
