The Swaras 'Sa' and 'Pa' are fixed, and here is how to get the other swaras from the melakarta number. Melakartas 1 through 36 have Ma1 and those from 37 through 72 have Ma2. The other notes are derived by noting the (integral part of the) quotient and remainder when one less than the melakarta number is divided by 6.
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
A mental calculator or human calculator is a person with a prodigious ability in some area of mental calculation (such as adding, subtracting, multiplying or dividing large numbers). In 2005, a group of researchers led by Michael W. O'Boyle, an American psychologist previously working in Australia and now at Texas Tech University , has used MRI ...
It was originally known as "HECKE and Manin". After a short while it was renamed SAGE, which stands for ‘’Software of Algebra and Geometry Experimentation’’. Sage 0.1 was released in 2005 and almost a year later Sage 1.0 was released. It already consisted of Pari, GAP, Singular and Maxima with an interface that rivals that of Mathematica.
The first scientific calculator that included all of the basic ideas above was the programmable Hewlett-Packard HP-9100A, [5] released in 1968, though the Wang LOCI-2 and the Mathatronics Mathatron [6] had some features later identified with scientific calculator designs.
The Mental Calculation World Cup 2014 was held from 10/10/2014 to 12/10/2014 in the Faculty of Mathematics in Dresden University of Technology, Germany. 39 mental calculators from 17 countries participated. The World Cup involved the following 5 main contests: Adding ten 10-digit numbers, 10 tasks in 7 minutes

In mathematics, Robinson arithmetic is a finitely axiomatized fragment of first-order Peano arithmetic (PA), first set out by Raphael M. Robinson in 1950. [1] It is usually denoted Q. Q is almost [clarification needed] PA without the axiom schema of mathematical induction. Q is weaker than PA but it has the same language, and both theories are ...
