ArithmeType Is Heavy, Wired, and Expensive. Nitrax Is Built for Everyday Math Writing.
ArithmeType’s own site shows a dedicated math keyboard with a separate cord, a large physical footprint, and a premium price point. That is a lot to ask when you already have a computer keyboard and just want to type math faster.
On the ArithmeType site, the main math keyboard is listed at $299 and described as a USB plug-and-play device that works alongside your computer keyboard with a built-in 3-foot USB-A cord.
That means an extra physical device on the desk, a wired setup, and a product that still sits beside your normal keyboard rather than replacing the need for everyday typing.
Why the ArithmeType model is hard to justify
It is expensive. It is wired. And it is clearly a separate math-only device, not a general writing keyboard that helps with math inside your normal workflow.
The product is also shaped around a narrow use case: a dedicated math input surface. That can be useful, but it is not the most practical setup for most students and teachers who want to type math in ordinary documents.

Wired desk clutterThe 3-foot USB-A cord makes it feel like another fixed device.

Narrow scopeIt is dedicated to math input, not a broader writing-first flow.
Why Nitrax is the sharper choice
Nitrax Mathematical Keyboard is the physical math keyboard that stays closer to how people actually write: notes, homework, reports, slides, and emails.
It is not trying to be a bulky specialty station. It is trying to make math symbols fast on the keyboard you already use with your computer.
