Manil Suri Q & A

Mathematician and author Manil Suri (University of Maryland Baltimore) visited St. Andrews Public School in Toronto and took questions from students and parents at the school's Math Community Evening, where young students shared their classroom learning with family, firends, and the wider community.

Questions asked:

1. [0:05] Why did they choose North for a compass to point to. Why were South, East or West not chosen?
2. [0:37] If parallel lines meet, are they really parallel lines anymore?
3. [2:32] Other than math, do mathematicians have any other interests?
4. [3:22] When can 2 + 2 = 5?
5. [3:53] Can you please share some unconventional methods of learning or understanding math basics other than bookish?
6. [4:29] We now know that odd numbers hide in squares. Where do mathematicians hide?
7. [5:06] Who created multiplication?
8. [6:02] What skill or strand is most important for this generation of kids, to take them into the future?
9. [6:57] Does pi go on forever?
10. [8:42] Would 3.333... eventually become a whole?
11. [9:43] Is zero and odd or an even number?
12. [10:34] How do calculators work?
13. [11:30] How were numbers created?
14. [12:51] Are calculators always right?
15. [13:57] Why are there pluses and equals between numbers like when you write 1 + 1?
16. [14:58] Isn't that BEDMAS where brackets go first and exponents second?
