Get the Algebramug. A sigma algebra (or σ-algebra) is to set algebras what sigma males are to males. The Borel hierarchy (the analog of the male hierarchy) is not a σ-algebra at any countable rank; instead the σ-algebra has the largest possible rank -- ω_1, the least uncountable ordinal (under suitable conditions e.g. the Polish space is uncountable. This is known as the non-collapse of the Borel hierarchy).
A σ-algebra is closed under countable union, countable intersection, and relative complement. This means σ-algebras arise naturally in the study of measure theory, where the measurable sets form a σ-algebra.

The algebra of Lebesgue-measurable subsets of R (i.e. the sets of real numbers with a well-defined "length", which is possibly infinity) form a sigma algebra.

Get the algebramug. This is what algebra does to nerds
in the parking lot
Normal Guy: Turn right to park here.
Nerd: -b plus or minus the square root of b^2-4ac/2a

Get the algebramug. That One Guy From Your Algebra Test, you already know who that guy is. Often named something along the lines of Ralph. They have superhuman abilities, often doing things like trading with other similar people. Many times, they will be buying 87 watermelons, and/or loaning/combining a certain number of watermelons with their friend who has a similar amount of watermelons. You may be asked to find the total number of watermelons they have combined.
That One Guy From Your Algebra Test:
Ralph has 69 watermelons, Sarah has 420 watermelons, if Ralph gives Sarah 40 of his watermelons, how many will she have?
John is walking to his friend's house. His friend lives 800 kilometers away. If John walks at a speed of 16 kilometers per second, how long will it take him to get to his friend's house? (leave your answer in seconds).
Alex is 30 years old. Alexa is 3000 years old if Amy's age is the mean of both of their ages, is she of legal age to purchase and conduct a Kenworth T680 Semi?
Fredrick is 30 feet tall, Enrique is 94 billion light-years tall, If Enrique stands up on planet Earth, how many galaxy clusters will he pass through before creating a supermassive blackhole?
Etc
