Since it is possible to find sequences of 36 consecutive integers such that each inner member shares a factor with either the first or the last member, 36 is an Erdős–Woods number. [11] The sum of the integers from 1 to 36 is 666 (see number of the beast). 36 is also a Tridecagonal number. [12]
For example, Bhaskara I writes: [36] ६ १ २ १ १ १ ० ४ ५ ९. which is the equivalent of 6 1 2 1 1 −1 4 5 9. and would be written in modern notation as 6 1 / 4 , 1 1 / 5 , and 2 − 1 / 9 (i.e., 1 8 / 9 ).
The final digit of a triangular number is 0, 1, 3, 5, 6, or 8, and thus such numbers never end in 2, 4, 7, or 9. A final 3 must be preceded by a 0 or 5; a final 8 must be preceded by a 2 or 7. In base 10, the digital root of a nonzero triangular number is always 1, 3, 6, or 9. Hence, every triangular number is either divisible by three or has a ...
Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:

A perfect power has a common divisor m > 1 for all multiplicities (it is of the form a m for some a > 1 and m > 1). The first: 4, 8, 9, 16, 25, 27, 32, 36, 49, 64, 81, 100 (sequence A001597 in the OEIS). 1 is sometimes included. A powerful number (also called squareful) has multiplicity above 1 for all prime
The 1-36 was conceived as a replacement for the One-design competition Schweizer SGS 1-26, when production of that model ended in 1979. [7] The 1-36 was also the last glider model that the company would manufacture. The completion of production of the 1-36 in 1982 marked the end of an era that started in 1930 with the Schweizer SGP 1-1. [1] [4]
The square root of 2 (approximately 1.4142) is the positive real number that, when multiplied by itself or squared, equals the number 2.It may be written in mathematics as , or /, and usually written as sqrt(2) in computer programming.
