The value of a teaching method is determined by the individual learner. Too often a new or different teaching technique is espoused as superior to others. I am a fan of manipulatives, having successfully used them with a number of struggling math students of various...

Division by zero is it really Impossible
By: Stanley Roberts
Dividing by zero should be narrowed down to elementary math and no need to try to use Einstein, calculus, or our wide world of infinity to explain this process.Yes, it is true that we do in calculus and trigonometry use 'i' or imaginary numbers...

Division by zero is it really Impossible
By: Rob Onion
A beautiful question and the most sought after answer no doubt. Dividing by zero is mathematically impossible, for now. Not too long ago we thought we couldn't land on the moon and we did that. The simple question is: how is it possible for us...

Scalars are quantities that need no direction to specify them, but vectors need direction to specify them. To properly understand the distinction, we must consider some examples. A few examples of scalars are mass, moment of inertia, magnitude of acceleration due to gravity, and speed...

Integers are real numbers that can be expressed without a fraction or decimal. Real numbers are part of the complex numbers, which include the imaginary numbers. The square root of a negative number is called an imaginary number. The natural numbers are the counting numbers...

To help you answer this question, I'm going to a little hypnotic regression... you are going baaaack in time... back to when you were in third grade studying fractions...Your teacher is cutting a cake as a tasty lesson in division. "If you want to...
Celebrate Pi Day on March 14
By: Steven Mars
Pi Day is celebrated the last day of the second week in March because March 14 is the third month fourteenth day of the year and 3.14 is the most common approximation of pi. It was discovered by Archimedes of Syracuse. One way to...
Division by zero is it really Impossible
By: Bryan Belrad
We are sometimes bothered by the question: 'what happens when you divide by zero?' What really stumps us, though, is not what the result is, it is how one goes about performing the action. How can one slice an apple in zero pieces, for...

The first thing to show is that Alegbra is only about one goal: "Finding the number or numbers that satisfy the equation or mathematical statement using any quick and useful method."This statement gives you a clear goal when you look at an algebra problem...
