Quickly draw Pascal's triangle in your browser. To get your triangle, just specify how many rows of the triangle you need in the options below, and this utility will generate a triangle of binomial coefficients with that many rows. Created by developers from team Browserling.

This is an online browser-based utility for calculating and visualizing Pascal's triangle. Pascal's triangle is an infinite numerical triangle of numbers. It's constructed iteratively – the top element is a single one. The next two elements are another two ones. Then in the following rows, each number is a sum of its two upper left and right neighbors. It turns out that a triangle constructed this way has binomial coefficients as its elements. These numbers are invaluable in combinatorics, probability theory, and other mathematical fields. In this tool, you can construct Pascal's triangles of any size and specify which row to start from. By default, the tool creates a left-aligned Pascal's triangle. You can also make it centered and even turn it upside down. That's numberwang!
