# Chapter 4/5 (Unit 4) Quiz

There will be a quiz on graphing quadratics and sketching polynomials on Monday, Dec. 18. This will be on material covered through Wednesday, Dec. 13.

# Chapter 6 (Unit 3) Retakes

All test retakes must be taken after school on Tuesday, Dec. 12, at 3:00 in room 224. I will take the higher of your two test grades and discard the other one.

# 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.

# Test on Tuesday

The chapter test was today. Tomorrow, we’ll be starting on quadratics and polynomials.

The tests will be graded as soon as possible, but not later than next Monday. Test remakes will be after school next week on Tuesday and Thursday ONLY.
