According to MathGoodies.com, zero is a neutral number or integer since it is neither negative nor positive. Whole numbers to the right of zero, or greater than zero, are known as positive integers. Whole numbers to the left of zero, or less than zero, are known as negative integers.
Know MoreTwo integers on a number line the same distance from zero are known as opposites, an example being -3 and +3. The term integers is defined as the "set of whole numbers and their opposites." According to Reference.com, non-negative integers or positive integers greater than zero, are also known as "natural numbers." Zero is also a natural number.
Learn more about NumbersPi is important in math because it describes how the circumference of a circle is in proportion to the diameter of a circle. To get pi, a mathematician divides the circumference of the circle by the diameter.
Full Answer >Pi is a mathematical constant and irrational number representing the ratio of a circle's circumference to its diameter with a value of approximately 3.1416. Even though mathematicians using computers are able to calculate an approximate value for pi to 2.6 trillion digits, its exact value remains unknown. The symbol for this constant is the lowercase Greek letter pi.
Full Answer >An extremely difficult math equation is the Jacobi-Madden equation, a^{4} + b^{4} + c^{4} + d^{4} = (a + b + c + d)^{4} where variables a, b, c and d can be any positive integer, negative integer or zero. The Jacobi-Madden equation is considered a Diophantine equation.
Full Answer >Phi is the 21st letter of the Greek alphabet and in mathematics, it is used as a symbol for the golden ratio. The golden ratio refers to a special number that is approximately equal to 1.618. It is also known as the golden section, golden mean, divine section, medial proportion, golden cut, extreme and mean ratio, golden number or divine proportion.
