That doesn't even work with Roman numerals and all of it is wrong. That's Randall Munroe - the author of xkcd - trolling idiots.
No, its correct.That doesn't even work with Roman numerals and all of it is wrong. That's Randall Munroe - the author of xkcd - trolling idiots.
The Romans did not have the addition sign or the equal sign. They literally wrote out plus and et instead. As for the concept of zero and decimal places? Those didn't reach Europe until after Muhammad ibn Musa Al-Khwarizmi invented algebra in the 9th century AD.No, its correct.
In the image, substitute the 1s for Is, the 5s for Vs, and the 10 for an X, and the math all adds up.
I + I = II
II + II = IV
IV + V = IX
Or...
1 + 1 = 2
2 + 2 = 4
4 + 5 = 9
So for example, 46 in Roman numerals would be XLVI, which would be 105051 under his system of translating numerals to numbers.
Yes, I know. Its also completely irrelevant to the joke made by xkcd.The Romans did not have the addition sign or the equal sign. They literally wrote out plus and et instead. As for the concept of zero and decimal places? Those didn't reach Europe until after Muhammad ibn Musa Al-Khwarizmi invented algebra in the 9th century AD.
He and I have a lot in common then.He also wouldn't know what any of it means.
