Algebra Definitions: Part 3

Math Made Easy has compiled a list of commonly used terms in Algebra.

Need help with algebra? You are not alone! Algebra is one of the most difficult subjects for many students, even those who are normally high achievers. But here's some good news: once a student becomes familiar with the special "language" of algebra, it can become one of the easiest, and even most enjoyable, things for them to do!

Algebra is based on a special kind of logic--once it clicks in students' heads, it becomes easy to apply to any type of problem. The trouble is, some students learn best at different paces, and in different environments, than others. For many, a 45-minute classroom session, surrounded by the distractions of their peers, is simply not the ideal way to learn.

Even if students pay close attention in class, they are liable to miss a lesson or a portion of a lesson for any number of reasons. And since math works like a chain, with one concept leading to the next, a "missed link" causes subsequent material to stop making sense. With Math Made Easy's innovative program of DVDs, students no longer feel embarrassed when they need to have a concept repeated to them. They simply rewind the disc to hear the information explained again!

Our sister site,, is the perfect companion to our DVDs, allowing users to download free practice tests, chart their progress, receive live help from online tutors, and watch streaming videos of algebra lessons. Our system guides students step-by-step through each concept, targeting weak areas while building overall comprehension. With all these tools at their disposal, even students currently receiving very poor or failing grades in algebra can earn As and Bs. Call 1-888-MATH-HELP, and receive your free consultation today!

Below is the third part of our Algebra list of terms. See ho many you ae familiar with!!

  • degree: A unit of angle measurement.
  • degree of a monomial: The sum of the degrees of the variables in the monomial.
  • degree  of a polynomial:  The greatest of the degrees of its terms after it has been simplified.
  • degree of a variable in a monomial:  The number of times that the variable occurs as a factor in the monomial.
  • difference:  See subtraction.
  • direct variation:  A function defined by an equation of the form y=kx, where k is a nonzero constant. We say that y is directly proportional to x. (See also quadratic direct variation.)
  • discriminate:  For a quadratic equation in the form ax 2 + bx + c = 0, the value of b2 --4ac is called the discriminant.
  • disjoint sets:  Two sets that have no members in common.
  • disjunction:  A sentence formed by joining two open sentences by the word or.
  • distance formula:  For any points P 1(x 1, y1) and P 2(x2,y2 ), P 1 P 2= the square root of (x 2 - x1)2 +(y 2 - y2)2.
  • divisible:  One polynomial is (evenly) divisible by another polynomial if the quotient is also a polynomial.
  • division:  For every real number a and every nonzero real number b, the quotient a divide b or a/b, is defined by a divide b = a x 1/b.
  • domain of a variable:  The given set of numbers that the variable may represent.
  • empty set:  The set with no members; the null set.
  • endpoint:  The starting point of a ray.
  • equation:  A statement formed by placing an equals sign between two numerical or variable expressions.
