## What is Calculator X?

Calculator X is a powerful calculator built for developers, students, and anyone who works with numbers beyond the basics.

PROGRAMMER'S CALCULATOR
Work seamlessly across decimal, binary, hexadecimal, and octal. Toggle individual bits directly on a 64-bit grid, perform bitwise operations (AND, OR, XOR, NOT), and watch all four bases update in real time as you type.

2D FUNCTION GRAPHING
Plot any mathematical function of x instantly. Pan and pinch-to-zoom to explore the curve at any scale. Perfect for visualizing equations, finding intersections, and understanding function behavior.

3D SURFACE PLOTTING
Enter any function of x and y and see it rendered as a live 3D surface. Rotate with one finger, zoom with a pinch, and pan with two fingers. Gradient coloring makes it easy to read the shape of any surface.

MATRIX CALCULATOR
Work with matrices up to 8×8. Perform addition, subtraction, multiplication, transpose, determinant, and inverse — all in one place. Results scroll so nothing gets cut off no matter how large your matrix is.

ALL FEATURES FREE
Every tool is available to every user, no subscription required.
