Question

algebra n.代数学 (1) 这个男孩做不出这道代数题。(2) 学习代数很容易。(3) 我在中学就学过代数学。 The noun algebra comes from Arabic word al jebr, meaning "reunion of broken parts," which appeared in the title of mathematician al-Khwarizmi's famous book on equations. In algebra you use basic arithmetic like addition and subtraction, but the quantities you're working with are often unknown — that's why they're represented by letters. You might remember solving algebra equations that look like this: a(b + c) = ab + ac. The letters a, b, and c all represent a number.
