A positive integer is a whole number greater than zero, and a negative integer is a whole number less than zero. Whole numbers are numbers without any fractions or decimals. These numbers are also called counting numbers.
Know MorePositive and negative integers have many uses in real life. The negative integer -16 may be used to describe a loss of $16 or 16 pounds. The positive integer +5 might be used to refer to a gain of 5 pounds. These numbers are also used with temperatures. The positive integer +32 is another way to say it is 32 degrees above zero, while the negative integer -3 is used to say it is three degrees below zero.
Learn MoreBabylonian mathematicians as early as the Sumerian Ur III period (21st to 20th century B.C.) used geometric methods to solve second-degree problems. Similar geometric methods solved quadratic equations in later Babylonia, Egypt, Greece, China, and India. Indian mathematician Brahmagupta (597-668 C.E.) was the first to give an explicit solution.
Full Answer >A double root occurs when a second-degree polynomial touches the x-axis but does not cross it. Both ends of the parabola extend up or down from the double root on the x-axis.
Full Answer >Plot holes are inexplicable contradictions in literature and film. They usually entail some sort of logical fallacy in either the author's narration or in the decisions made by a character.
Full Answer >The only difference between the set of positive integers and the set of nonnegative integers is the inclusion of zero in the set of nonnegative integers. Zero is neither a positive number nor a negative number. It is considered a rational number, an even number and a real number.
