Example of Ancient Egyptian multiplication

21  ✕  15 = 315

1   ✔                                             15   

2                                                   30

4   ✔                                             60

8                                                   120

16  ✔                                            240

---------------------------------------------------------------------

1 + 4 + 16 = 21                            15 + 60 + 240 = 315

Reflect on the reading: Medieval Islam Mathematics

Reflecting on the reading, it’s fascinating to see the significant role that the House of Wisdom in Baghdad played during the Islamic Golden Age. It was more than just a library; it was a vibrant center of translation and research where scholars translated Greek and Hindu treatises into Arabic and conducted their own research. This institution was instrumental in preserving and expanding knowledge during this period. The contributions of Muhammad ibn Mūsā al-Khwārizmī, a renowned Muslim mathematician, are particularly noteworthy. Al-Khwārizmī popularized the use of Hindu-Arabic numbers and the number zero, introduced the concept of algebra, and demonstrated the use of geometry to prove algebraic results. His treatise on Hindu-Arabic numerals played a pivotal role in popularizing these numbers and the concept of zero, which revolutionized mathematical computations. Lastly, the practical application of algebra, as demonstrated in Al-Khwārizmī’s treatise, Kitab al jabr wa’l-muqabalah, is ...

Russian Peasant method vs Ancient Egyptian method

The Russian Peasant method and the Ancient Egyptian method are related because they both employ the same fundamental mathematical concept of decomposing numbers into binary form and then using halving, doubling, and summation to perform multiplication. They are different interpretations of the same basic technique. Edited For example: Multiply 17 by 12 using the Russian peasant method 17 in binary is 10001 and 12 in binary is 1100. Left             Right 10001           1100 01000           11000 00100           110000 00010           1100000 00001           11000000 Now, cross out the rows where the number in the left column is even. Left             Right 10001           1100 00001           11000000 Finally, ...
