The Rhind Mathematical Papyrus, [1][2] an ancient Egyptian mathematical work, includes a mathematical table for converting rational numbers of the form 2/ n into Egyptian fractions (sums of distinct unit fractions), the form the Egyptians used to write fractional numbers. The text describes the representation of 50 rational numbers.
Angle-based special right triangles are specified by the relationships of the angles of which the triangle is composed. The angles of these triangles are such that the larger (right) angle, which is 90 degrees or π 2 radians, is equal to the sum of the other two angles. The side lengths are generally deduced from the basis of the unit ...
Psalm 63. Psalm 63 is the 63rd psalm of the Book of Psalms, beginning in English in the King James Version: "O God, thou art my God; early will I seek thee". In the slightly different numbering system of the Greek Septuagint version of the Bible and the Latin Vulgate, this psalm is Psalm 62.
In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . Many writers begin the sequence with 0 and 1, although some authors start it from 1 and 1 [1][2] and some (as did Fibonacci) from 1 ...
Knuth's up-arrow notation. In mathematics, Knuth's up-arrow notation is a method of notation for very large integers, introduced by Donald Knuth in 1976. [1] In his 1947 paper, [2] R. L. Goodstein introduced the specific sequence of operations that are now called hyperoperations. Goodstein also suggested the Greek names tetration, pentation ...
If the hundreds digit is odd, the number obtained by the last two digits must be 4 times an odd number. 352: 52 = 4 x 13. Add the last digit to twice the rest. The result must be divisible by 8. 56: (5 × 2) + 6 = 16. The last three digits are divisible by 8. [2][3] 34,152: Examine divisibility of just 152: 19 × 8.
2 Peter 3 is the third (and final) chapter of the Second Epistle of Peter in the New Testament of the Christian Bible. The author identifies himself as "Simon Peter, a bondservant and apostle of Jesus Christ". [1] The epistle is traditionally attributed to Peter the Apostle, but some scholars consider it to be a work of Peter's followers ...
