Desmos is not just a calculator; it's the most beautiful and intuitive tool for exploring the visual world of algebra.

First, just type any equation into the expression bar. Watch it instantly appear on the graph. y=2x+1. Boom.

Click and drag the graph to pan around. Use your scroll wheel to zoom in and out. It's that easy.

Click on any interesting point on your graph - like an intercept - and Desmos will show you the coordinates.

The magic feature: Sliders. Type 'y=mx+b'. Desmos will ask if you want to create sliders for 'm' and 'b'. Say yes.

Now, move the 'm' slider and watch the slope of your line change in real-time. Move the 'b' slider and watch it shift up and down.

This is it. This is how you build deep, intuitive understanding of how functions work.

You can graph multiple equations at once to see where they intersect, a visual way to solve systems.

You can use inequalities to shade regions of the graph, making complex ideas simple.

Desmos transforms graphing from a tedious plotting exercise into a thrilling, interactive exploration. Go play.
