The formula calculator concept can be applied to all types of calculator, including arithmetic, scientific, statistics, financial and conversion calculators. The calculation can be typed or pasted into an edit box of: A software package that runs on a computer, for example as a dialog box. An on-line formula calculator hosted on a web site.
310 is an even composite number with 3 prime factors. [1] 310 is a sphenic number meaning that it has 3 prime factors. [2] 310 is a noncototient number which means that m − φ(m) = n has no solution for n=310. [3] 310 is the number of Dyks 11 paths with strictly intersecting peaks. [4] 310 in base 6 is 1,234. The sum of the divisors of 310 is ...
The simplest example given by Thimbleby of a possible problem when using an immediate-execution calculator is 4 × (−5). As a written formula the value of this is −20 because the minus sign is intended to indicate a negative number, rather than a subtraction, and this is the way that it would be interpreted by a formula calculator.
(Similar plans were being considered to provide relief to the 310, 415, 510, 760 and 818 area codes as well; however, due to number rationing, all were postponed indefinitely and later permanently cancelled.) Nevertheless, even with numbering conservation measures in place, the NANPA determined in 2003 that 909 would indeed require relief. [3]
[1] In 1950, the boundaries of the numbering plan area were redrawn to produce a division of the northern and central parts along a north–south-running dividing line. Numbering plan area 415 became the coastal region from the North Coast to the Oregon border, while 916 was redrawn to comprise the northeastern corner of the state. [ 2 ]
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
Area code 863 is a telephone area code in the North American Numbering Plan for a part of south-central Florida.The numbering plan area comprises the Heartland, as well as Polk County in Central Florida.
A detailed contemporary collection of constructions for the determination of lengths from a distance using this instrument is known, the Dioptra of Hero of Alexandria (c. 10 –70 AD), which survived in Arabic translation; but the knowledge became lost in Europe until in 1615 Snellius, after the work of Eratosthenes, reworked the technique for ...
