 After finishing this writing, I cannot answer all the questions deeply. I hope to receive the feedbacks from the instructor and all my classmates. Thank you  After reading this article, I realize that the mathematical word problem which appeared thousand years ago are also used at the present. For me, they are even more difficult. Look back the mathematical word problems history, these mathematical word problems came from the real life, so they are so practical. The difference is that all the units which were used in the past are totally different from the present. Beside the word problems connecting with real life, there are unreal problems. “The impractical nature of these stories calls into question their referentiality in pointing to “real world” situations and casts doubt upon the serious practicality of even those more plausible problems” (Susan, p.5). 1// Our interpretation relies on our familiarity with contemporary algebra because all the math word problems belong ...

   Hi everyone,  Figure 1.1 makes me really surprised. It shows me how mathematics developed over the ages. Greece à Discovery of Greek learning à Europe and her culture dependences. In the past, I think that the math history from Greek but it not true. It came from Egypt and Mesopotamia. This diagram shows that there is a transportation from Greek to Europe. I am so surprised about Baghdad, Iraq. This is the first time I hear that math history involves to Iraq. House of Wisdom was built in Baghdad with a large library for manuscripts that had been collected from virous sources. (p.11) “In both Egypt and Mesopotamia there existed well-developed written number systems as early as the third millennium BC. The peculiar character of the Egyptian hieroglyphic numerals led to the creation of special types of algorithms for basic arithmetic operation” (George, 13). This sentence helps me to understand the history of algorithm After reading this article, I understand th...

  1/ 60 is a special number because 1 minute = 60 second and 1 hour = 60 minutes. This number has many factors: 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. For me, number 10 is also one of the factors of number 60. Number 10 has only two factors 2/ 6 x 60 = 360. This is number degrees of a circle. The cycle of 60 in Chinese zodiac is formed by the 5 elements and the 12 animals. According to the ancient tradition of Dogons, the world has been created by the voice of Ama, exactly as the Bible which tells that it has been created by the Word of Jehovah. The time and the space have been created by the bad angel Ogo by walking 8000 times  60  steps during  60  periods, that is to say 28800000 steps. ( The Nu)mber 60: Properties and Meanings (virtuescience.com) 3/+ Product of the  3, 4, 5 Pythagorean right triangle numbers = 3 x 4 x 5 = 60 ( The Number 60: Properties and Meanings (virtuescience.com) ) + The 60 meaning is reminding you that it’s...

 Hi everyone   For many students, math is difficult and boring because students work a lot with numbers, formulars or sometimes they need to remember these formulars. Actually, in order to have these formulars and knowledge of math, many mathematicians spent many years to discover them. History of math is important for both teachers and students. If the students ask the teachers where this math knowledge comes from, the teachers will answer this question easily if they know about the history of this knowledge. Knowledge of math comes from our real life. Knowing the history of math knowledge makes us more “emotional” and understand about that knowledge. For example, number 0 is a number, but for me – a teacher, number 0 is a wonderful number because I know about the history of this number. “[H]istorically inspired exercises may stimulate the student’s interest and contribute to curricular enhancement alongside those exercises and problem which may seem more artificially desig...
