# It Was Greek To Me, Part 2

*(We are learning about sigma notation in math, and our teacher has just explained that sigma (Σ) is the Greek letter ‘S’ and what it means for the notation.)*

**Student #1:** “So, did the ancient Greeks like use sigma to write ‘S’ in their language?”

**Teacher:** “Yes.”

**Student #1:** “And all the other math Greek letters too? Like pi and tau and theta and stuff?”

**Teacher:** “Yes. They still do.”

**Student #2:** “Wait, what? They still use the Greek alphabet?”

**Teacher:** “Yes, the modern Greek alphabet is still the same as the ancient one. All these letters are real letters in their alphabet.”

**Student #2:** “Oh. I thought they used the Cyrillic alphabet. I thought Greek letters were just for math now.”

**Student #1:** “How do Greek people do math? Don’t they get confused?”
