7. What's the score? (Type two math nouns)
Academic performance is calculated by scores. To ask "how much", you can put it another way and ask "geometry?" In ancient mathematics books in China, when you ask how many items there are, you always ask, "Does everything have geometry?" Until now, in some dialects, the price of asking things is still "geometry?" So, asking "What's the score" is equivalent to asking "Fraction, geometry?" The answer is two mathematical terms: fraction and geometry.
