# Other Cultures and Math

I’ve mentioned in class that German uses slightly different symbols than we do. Here’s a screen shot from a German video on linear functions.

Most of this is recognizable. The 1s are different than ours, but there are two bigger differences:

1. The original problem is: Given the point $$P(1, 2)$$ and the slope $$m = -2$$, what is the graph? In this case, the point is given as $$P(1|2)$$.
2. In the last step of solving for b, instead of writing $$+2$$ on both sides, the instructor wrote $$| +2$$ to the right of the entire equation.

I find it interesting to look at how other countries and cultures represent mathematics. The notation is indeed a language, and like any language there are variations around the world. The underlying concepts are universal, though.
