Math is easier with Magic Number.

When you can see math properly, able to type what you think, and do everything intuitively, math becomes a breeze.

From everyday math to advanced science, Magic Number lets you do more with less effort — whatever your level.

Here’s what you will enjoy:

See better — your eyes deserve more

•  See math properly and beautifully.
    Say no to messy ((8*sin(30))^(1/4)/5)*arcos(pi)
•  See the whole expression at any size.
    Everything is crystal clear and easy to understand.
•  See better results with superior formats.

Type naturally — no more mental barriers

•  Type math as you see it.
    For 2 sin 30 + √ 9, just type ‘2 sin 30 + √ 9’
    No more backward thinking ‘2 x 30 sin + 9√’
    And no more awkward syntax ‘2 * sin(30) + sqrt(9)’
•  Type fast without touching the mouse.
    You get lots of handy shortcuts like X for multiply.
•  Edit without thinking.
    Made a mistake? Just click and type over it.

Calculate intuitively — with extra smartness

•  You can deal with time:
    8:30 + 0:45 = 9:15
•  In fact you can deal with all kinds of numbers:
    fractions, percentages, complex numbers, and more.
•  You can let Magic Number do the algebra:
    Enter ‘100 – ? = 55’. You get ‘? = 45’
    Enter ‘240 – ? % = 192’. You get ‘? = 20’

Do more with less effort

•  Want to make sense of a list of numbers?
    The List feature gives you the sum, tax, and statistics
    with couple of clicks. It’s like a mini speadsheet.
•  The History lets you go back and reuse the past.
    You can even compare results.
•  You can export expressions beautifully as PDFs.
    This means you have a simple equation editor.

Go beyond calculators

•  Over 100 functions
•  25 digits accuracy
•  10 memories (variables)
•  4 customizable tax rates
•  Over 50 scientific constants
•  Statistics
•  Linear regression
•  Matrix (Inverse, determinant, Gauss-Jordan Elimination)

And much more.

Magic Number is the best calculator for macOS

Magic number is the best calculator app available without question. I’ve used Magic Number for calculus, chemistry, and physics at UC Berkeley and I have no idea how I would get through those classes with the stock calculator. Magic Number is incredibly intuitive and easy-to-use and has tons of great functions that make complex calculations much easier to do compared to a manual calculator.

Perhaps even more importantly, the developer is incredibly responsive and helpful. The app is updated with new features regularly and he has even implemented features that I’ve suggested. On top of that, he even emails me to let me know that those features have been added. If you’re looking for a better calculator, I would completely recommend Magic Number. It’s an amazing app and a great example of thoughtful design and excellent software development.

Honestly awesome

I’m just starting an MBA program online and have no math, economic, or finance background (feel free to judge - I’m judging myself, too!).

Magic Number allows me to look down at the book and type exactly what I see. It’s truly terrific.

One thing I’d like to see added (and it’s probbly in there) is a way to create and save formulas so I can just open a sidebar and click on whatever it is I’m trying to solve for.

That said, this feature isn’t necesary for me to give an inexpensive calculator a 5-star rating.
