Pi.Mathematika | Math Learning on Instagram: "why the Factorial of O is 1 (0!=1) ? The factorial of zero, written as 0!, equals 1 because of how patterns in mathematics work. When you multiply numbers in decreasing order (like 5! = 5×4×3×2×1), each step follows a consistent rule. To keep that pattern valid, mathematicians define 0! = 1. It also fits perfectly in combinatorics—there’s exactly one way to arrange zero objects: doing nothing! This definition ensures formulas in algebra, calculus, an

The AI Mod on Instagram: "Why do computers use binary — just 0s and 1s — instead of a faster trinary system with 0, 1, and 2? 🤔 Harvard computer scientist David J. Malan breaks it down perfectly 👇 Binary isn’t about being old-fashioned — it’s about being simple, reliable, and stable. Computers run on electricity, and it’s far easier to detect whether a signal is on or off (0 volts or 3 volts) than to measure uncertain middle states like 1.5 volts. Trinary could be more efficient in theory, but
