... 11. A student asked his math teacher, “How many children do you have, and how old are they?” “I have 3 girls,” replied the teacher. “The product of their ages is 72, and the sum of their ages is the same as the room number of this classroom.” Knowing that number, the student did some calculations an ...

... Hex to Signed Decimal Conversion Rules Given a Hex number, and you are told to convert to a signed integer (either as signed magnitude, 1s complement, 2s complement) STEP 1: Determine the sign! If the Most Significant Bit is zero, the sign is positive. If the MSB is one, the sign is negative. This ...

Approximations of π
Approximations for the mathematical constant pi (π) in the history of mathematics reached an accuracy within 0.04% of the true value before the beginning of the Common Era (Archimedes). In Chinese mathematics, this was improved to approximations correct to what corresponds to about seven decimal digits by the 5th century.Further progress was made only from the 15th century (Jamshīd al-Kāshī), and early modern mathematicians reached an accuracy of 35 digits by the 18th century (Ludolph van Ceulen), and 126 digits by the 19th century (Jurij Vega), surpassing the accuracy required for any conceivable application outside of pure mathematics.The record of manual approximation of π is held by William Shanks, who calculated 527 digits correctly in the years preceding 1873. Since the mid 20th century, approximation of π has been the task of electronic digital computers; the current record (as of May 2015) is at 13.3 trillion digits, calculated in October 2014.
