Euler’s identity, beauty in a formula.

Sometimes called "the most beautiful equation in mathematics", Euler's Identity connects together 5 seemingly unrelated mathematical constants: e, π, i, 0, and 1. Do you know the proof of this identity?

US inflation remained at a higher-than-expected 2.7% in December | CNN Business US consumer prices rose 2.7% annually in December, closing out a year that saw slight progress on inflation but continued affordability concerns for many Americans.

Prices are still rising, groceries are more expensive, tariffs are paid by consumers, and Trump is still gaslighting Americans.

गणित की दुनिया में 0 से अनंत तक की यात्रा कभी समाप्त नहीं होती। हर संख्या के बाद एक और बड़ी संख्या मौजूद होती है। यही कारण है कि गणित में “आख़िरी नंबर” जैसा कोई सिद्धांत नहीं है। संख्या रेखा सकारात्मक और नकारात्मक दोनों दिशाओं में अनंत तक फैली होती है। यह अवधारणा हमें सिखाती है कि संख्याएँ बिना किसी सीमा के बढ़ती और घटती रह सकती हैं।
