This is primarily a list of Greatest Mathematicians of the Past, but I use birth as an arbitrary cutoff, and two of the "Top " are still alive now. Click here for a longer List of including many more 20th-century mathematicians. Click for a discussion of certain omissions.

Despite what many high school students believe, you need to know relatively few formulas for the New SAT Math section. The reason why there are so few formulas necessary for SAT Math is that the SAT is meant to test your reasoning skills more than your ability to memorize though in some cases, of course, memorization is necessary.

There are always multiple avenues to the solution of a problem, and I teach my students how to take a consistent, accurate approach that utilizes a minimum of formulas and takes the path of least resistance to each answer.

Usually, this involves solving the problem differently than you would in math class, stressing technique and common sense over pure memorization. Take, for example, the distance formula.

Well, no worries, because the distance formula is completely useless on the SAT--and it's just a rearranged Pythagorean theorem anyway. The Pythagorean theorem is easier, more basic, and less prone to mistakes than the distance formula. So unless you are a whiz at the distance formula and never make careless mistakes on math questions, I would stick with the advice of Mr.

That being said, there are still a few things you must know by heart on test day.

Also know what the discriminant is. If the discriminant is ZERO, then there is 1 real root. Mean is the same as average.

Median is the number in the middle after rearranging from low to high.

In the case that the list has no true middle because it has an even number of terms, find the average of the middle two. Multiple modes are possible if there is a tie for greatest frequency: Integers are whole numbers, including zero and negative whole numbers.

Think of them as hash marks on the number line. Remember that -3 is less than -2, not the other way around sounds simple but is a common mistake.

Prime numbers are positive integers that are only divisible by themselves and the number 1. Be able to list all the primes you between 1 and 50…remember that 1 is not a prime and there are no negative primes.

By the way, 51 is not prime…that question actually showed up on a recent SAT. What, you forgot your times tables for 17? The prime factorization of 18, for example, is 3 x 3 x 2. These are particular types of Right Triangles that just happen to have exact integers as sides.

The SAT loves to use them, so know them by heart and save yourself the trouble of calculating all those roots.A Time-line for the History of Mathematics (Many of the early dates are approximates) This work is under constant revision, so come back later.

Here are my online notes for my Algebra course that I teach here at Lamar University, although I have to admit that it’s been years since I last taught this course.

Completing the Square: Ellipse Equations One general format of an ellipse is ax 2 + by 2 + cx + dy + e = 0. But the more useful form looks quite different. Algebra I is an entirely new course designed to meet the concerns of both students and their parents. These 36 accessible lectures make the concepts of first-year algebra - including variables, order of operations, and functions-easy to grasp.
