## What is Formulator+?

Formulator is a fast, clean formula calculator you can build yourself.

Create “bars” for variables, type formulas like area = pi*r^2, and Formulator updates everything instantly as you change inputs. 

Save multiple calculators for different classes, projects, or real‑life problems—then reuse them anytime.

What you can do:

- Build reusable calculators in seconds (engineering, school, finance, fitness, DIY)
- Chain formulas across multiple variables (change one number → see all results update)
- Use powers, parentheses, and common functions (like sqrt, sin, cos, log)
- Create quick calculators from equations (example: a^2 + b^2 = c^2)
- Keep multiple saved “formulators” for different topics

Perfect for:

- Students: geometry, physics, algebra, homework checks

- Engineers & makers: quick what‑if calculations and design sanity checks

- Anyone who wants a simple way to organize formulas without spreadsheets
