| Jun 17, 2018 at 9:18 | comment | added | bof | Didn't Euclid add two equations when he proved the theorem of Pythagoras? The square of the hypotenuse is the sum of two rectangles; each rectangle is equal in area to the square of one of the legs; adding those two equations, the square of the hypotenuse is equal to the sum of the squares of the legs. | |
| Jun 17, 2018 at 9:04 | comment | added | Ben McKay | I don't think you can ever get a clear answer to a question like this, because the notion of equation was not very clearly defined before the invention of the equals sign. The mathematics of the past is very vague, unlike our clear contemporary definitions. | |
