Remaining true for people in need

No advertisements, no purchases, no popups, fraction functionality, everything that you would need from a functional calculator without the bloat of other apps
The only thing that’s truly lacking from this is a step by step process and explanations

AMAZING! But 1 problem I want to address...

This Calculator Is probably the best one I have but one problem is the [ans]block which is super annoying to use, instead use the "=" sign and to use it, type after it.

Clean, fast and Stress free Math Calculator

Desmos Scientific Calculator has been a game-changer for my stats and calculus classes. The interface is clean, intuitive, and way faster than my old handheld. I love how it handles fractions, trig functions, and even complex expressions without lag. Graphing isn’t available, but for quick homework checks and exams where graphing isn’t allowed, it’s perfect. The history view saves so much time when fixing mistakes. Best free scientific calculator I’ve used — no ads, no clutter. Makes math feel less stressful and way more accessible.

This is an amazing calculator app.

I love how amazing Desmos’s scientific calculator is. It is good for education and even for everyday math. I love how it can do many things many other calculators cannot do, like fractions, variables when given a value, and more. I even like Desmos’s scientific calculator more than its graphing calculator. This app could even be better if it solved with variables even when not given the variable a value (like 5(x+2)=5x+10), but still it is amazing.
