Latest update:

These tools cover the math tasks that do not fit a single formula family: step-by-step division, coordinate geometry, color encoding, and small linear algebra. The long division calculator shows every step — quotient, remainder, and a decimal check — so the answer is never a black box. The slope calculator finds the rate of change between two points and reports whether the line rises, falls, stays flat, or is vertical. For screen colors, the color format converter translates between RGB, HEX, and HSL. And the matrix calculator handles 2×2 addition, subtraction, multiplication, determinant, and transpose. Pick the operation that matches your problem; more unusual math and science tools live in the Math & Scientific collection.

Frequently asked questions

What color formats does this calculator convert?
The calculator converts between RGB channels, HEX channel output, and HSL input. RGB and HEX channel modes use red, green, and blue values from 0 to 255. HSL mode uses a hue angle plus saturation and lightness percentages, then returns copy-ready HEX, RGB, and HSL strings.
Is HEX a different color model from RGB?
No. Six-digit HEX is usually the same red, green, and blue channel data written in base 16. The first two hex digits encode red, the next two encode green, and the last two encode blue. RGB 51, 102, 153 and HEX 336699 describe the same color.
How does HSL describe a color?
HSL represents color with hue, saturation, and lightness. Hue is an angle around the color wheel, saturation describes how vivid or gray the color is, and lightness describes how close it is to black or white. It is often easier for design adjustments than raw RGB channels.
