algebra
Other forms: algebras
If the math equation you're doing has letters or other symbols that stand for numbers, you're likely doing algebra. You probably took your first algebra class early in your high school years.
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.

As languages change, so do pronunciations. Here are some words that have gone through relatively recent shifts in pronunciation or whose spelling is a mystery unless one knows a bit about the history of how they were pronounced. There are also a few words where the only thing that has changed is the stress of the syllables. In most cases, rhyming words or phrases, which are just useful for their sound and are not intended to mean anything, are given to provide a sense of how these different pronunciations sounded.
