The golden ratio in mathematics is the irrational number (1 + sqrt 5)/2. A decimal approximation of the number is 1.618. The German astronomer Johannes Kepler and his contemporaries were the first to call it the golden ratio.
A:A distance of 500 meters is the same as a distance of 0.31 miles. The one-step conversion of meters to miles is found by multiplying the number of meters by 0.00062137.
A:A landmark number is a number that makes math simpler by virtue of it being easy to relate to and calculate with, such as the number "10." Most landmark numbers are multiples of 10.
A:A number is a theoretical concept, and a numeral is the way that people denote that concept. A numeral contains one or more written symbols, but a number can be expressed in a range of ways. Number and numeral are often used interchangeably, but there is a slight difference between them.
A:According to Joy of Pi, the value of pi to 100 decimal places is expressed as 3.1415926535897932384626433832795028841971693993751058209749445923078 164062862089986280348253421170679. Pi is an irrational number with a limitless, non-repeating decimal expansion.
A:A non-real, or imaginary, number is any number that, when multiplied by itself, produces a negative number. Mathematicians use the letter "i" to symbolize the square root of -1. An imaginary number is any real number multiplied by i. For example, 5i is imaginary; the square of 5i is -25.
A:Every integer is not a whole number, but every whole number is an integer. An integer is any number, positive, negative or zero, that is able to be represented without a fraction or decimal, according to Reference.com. The number of possible integers is infinite.
A:A whole number belongs to the set of integers that are equal to or greater than zero. For example, the set of numbers {0, 1, 2, 3, 4, 5, ...} contains all of the whole numbers.
A:A Roman numerals list includes Hindu-Arabic numerals with a corresponding set of symbols. The letters I, V, X, L, C, D and M are used as symbols by Romans in a unique system of representing numbers.
A:The prime numbers less than 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97. A prime number is any number that is only divisible by itself and 1. The number 1 is not considered a prime number.
A:Pi is a real number, as all numbers that exist on a number line are real. Real numbers include all rational and irrational numbers; pi is defined as an irrational number.
A:Zillion has an indeterminate number of zeroes. Despite the popular misconception, zillion actually is not a true number. Rather, zillion is defined as an indeterminately large number.
A:Standard notation is when a number is completely written out using numerical digits. Some examples of numbers written in standard notation are 64,100 and 2,000,000.
A:A linear pattern exists if the points that make it up form a straight line. In mathematics, a linear pattern has the same difference between terms. The patterns replicate on either side of a straight line.
A:The Mayan number system is a base-twenty system that was developed by the Mayan civilization around the fourth century A.D. Only three symbols are used to represent all numeric values: a shell for zero, a bar for five and a dot for one. These symbols are arranged in columns that are read from top to bottom, and the columns are arranged in powers of 20.
A:To simplify a radical square root expression, identify any factor that is a perfect square, and remove it from underneath the radical sign, replacing it with its square root. For example, to simplify the square root of 63, identify that 63 is the product of 9 and 7. The square root of 9 is 3, so remove 9 from underneath the radical sign. Write the number 3 next to the square root of 7 to complete the simplification.
A:In spiritual studies, 444 symbolizes angelic protection and divine messages. According to Doreen Virtue, author of "Angel Numbers," when an individual encounters the combination of 444, he is surrounded by multiple angels and there is nothing to fear.
A:A non-integer is a number that is not a whole number, a negative whole number or zero. It is any number not included in the integer set, which is expressed as { ... -3, -2, -1, 0, 1, 2, 3, ... }.
A:The Feynman point is a sequence of six nines commencing at the 762nd place of the decimal representation of pi. The Feynman point is named after the theoretical physicist Richard Feynman.
A:Things that come in groups of seven include the days of the week, the cervical vertebrae of most mammals and the seven deadly sins. The number is frequently used for groups in religious contexts, such as in the number of levels of heaven in Islam.
