   en.wikipedia.org/wiki/Everyday_Mathematics

   Everyday Mathematics curriculum was developed by the University of Chicago School Math Project (or UCSMP ) [1] which was founded in 1983. Work on it started in the summer of 1985. The 1st edition was released in 1998 and the 2nd in 2002. A third edition was released in 2007 and a fourth in 2014-2015. [2] A new one was released in 2020, dropping ...

3. Order of operations - Wikipedia

   en.wikipedia.org/wiki/Order_of_operations

   [2] [3] Thus, in the expression 1 + 2 × 3, the multiplication is performed before addition, and the expression has the value 1 + (2 × 3) = 7, and not (1 + 2) × 3 = 9. When exponents were introduced in the 16th and 17th centuries, they were given precedence over both addition and multiplication and placed as a superscript to the right of ...

   The four color theorem and optimal sphere packing were two major problems of discrete mathematics solved in the second half of the 20th century. [44] The P versus NP problem, which remains open to this day, is also important for discrete mathematics, since its solution would potentially impact a large number of computationally difficult ...

   Rudin noted that in writing his textbook, his purpose was "to present a beautiful area of mathematics in a well-organized readable way, concisely, efficiently, with complete and correct proofs. It was an aesthetic pleasure to work on it." [2] The text was revised twice: first in 1964 (second edition) and then in 1976 (third edition).

7. Group (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Group_(mathematics)

   For example, the symmetric group on 3 letters is the group of all possible reorderings of the objects. The three letters ABC can be reordered into ABC, ACB, BAC, BCA, CAB, CBA, forming in total 6 (factorial of 3) elements. The group operation is composition of these reorderings, and the identity element is the reordering operation that leaves ...
