What does this tool do?

Every number is the sum of the two above it, and each row holds the binomial coefficients for that power. Values are exact even when they have dozens of digits. Use it for probability, combinations and binomial expansion.

Everything runs in your browser, so nothing you enter is uploaded or stored.
