Why Isn't 1 a Prime Number

A number divisible only by 1 and itself is considered a prime number. 1 seems to conform to the definition; it is divisible by 1 and itself and by no other number. But the definition of prime numbers excludes 1. Why?

Many people think it's because, in the case of 1, 1 and itself are the same number. But this is far from the truth.

Bisection Method of Finding Square Roots

While you already know how to find the square root of a number, you might not be able to describe the process efficiently and precisely to a computer. This could mean embarrassment if you are a computer programmer. Knowing an algorithm is also required of a mathematician. Moreover, knowing something new is always good for knowledge-seekers (which I assume you are if you are reading my blog).

In this post, we will look at a good-enough method of finding square roots, known as the bisection method.

The Two Types of Bad Bosses

According to the new chapter from Research in Occupational Stress and Well-Being, titled Stress, Well-Being, and the Dark Side of Leadership, bad bosses fall into two categories, or rather two ends of the spectrum.

In this post, we will discuss what those two ends are.

Quadratic Equations

In elementary algebra, any equation of the form ax^2 + bx + c = 0 is termed as quadratic equation. In the equation, x represents an unknown value while a, b, and c represent known values. The value of a must not be 0.

In this post, you will learn how to solve quadratic equations and their usage in the real-world.
