How did imaginary numbers get their name?
Rene Descartes came up with the word imaginary in 1637 to describe them. It was a derogatory term. He (and many other mathematicians of that age) did not like imaginary numbers. Many people didn't believe in them, because they were not real.
What is the math term for a number a variable or a product of numbers and variables?
Term- a number, a variable, or a product of numbers and variables.
What is the term for numbers formatted with a decimal point?
The set of real numbers.
What is the term for numbers with more than two factors?
Composite numbers are the numbers that have more than two factors.
What is the median of the first 15 composite numbers?
First 15 composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24 and 25. In order to find median for a set of numbers we have to arrange numbers in order: Since the the first 15 composite numbers are already in order so we need not to rearrange. Terms are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24 and 25. Median is the middle value. Since there are 15 terms then the middle term is the 8th term which in this case is 15. So, the median is 15.

They are prime numbers.
Which term did British prime minister Winston churchill use to describe the imaginary barrier separating communist countries from democracies?

What are complex or imaginary numbers?
An imaginary number is a number, which when squared, gives a negative real number. Any positive or negative real number, when squared, will give a positive real number. Imaginary numbers were originally conceived (around the 1500's) to provide solutions to equations which required there be a solution to the square root of a negative real number. Originally, that was the only purpose that they served, so they were given the term imaginary. The imaginary numbers were shown to be graphically at a 90° angle to real numbers. Complex numbers are the combination of real and imaginary numbers, and can be plotted graphically on a complex plane, just like you would plot x and y coordinates on a regular 2-dimensional plane.Through the work of Euler in the 1700's and others, a relationship between imaginary numbers and the behavior of waves and oscillating motion was worked out. See related link for some interesting information about imaginary and complex numbers.
Who discovered complex numbers in mathematics?
That's difficult to say. Rafael Bombelli defined an imaginary number in 1572, but Rene Descartes actually gave the term imaginary. Nobody seemed to have much use for them until the work of Euler and Gauss in the 1700's and 1800's. This information I got from the Wikipedia article on Imaginary Numbers.

What does Term mean when using square and triangle numbers?
Each term is a square or triangular number. In the context of the sequence of square numbers, the first term is the first square number, the second term is the second square number and so on.
