Who Wants To Be a Mathematician
10 things that I've learned about mathematics
1) The Pythagorean Theory is only true if it is on a flat plain
2) The Pythagorean Theorem is not true on the North Pole
3) Math is all about proof and evidence
4) Primitive Pythagorean triplets are only if the numbers go in order, for example 3,4 and 5
5) To get a million dollars solve the question y = x3 + ax +b?!!??!
6) The integers from 1-100 was discovered by a man named Carl Gauss
7) Mathematicians=explorers and discoverers
8) Millionaires=just people with a lot of money
9) Half of 2^4n^2=2^4n^2^-1
10) Math can be extremely confusing sometimes!!!
What did I learn from the talk?
...........and a Millionaire too........
I learned that math is an extremely hard subject. There are many different forms of question and many numbers. I also learned that math is about proof and evidence. The speaker gave us some questions and asked us how to figure it out. The questions were really difficult for example:
This question took us a long time to figure out and it was very complicated. At the end when the speaker was finished explaining I tried retracing the step, but was still completely and utterly lost. At the end of the talk though he told us that he would choose to be a mathematician any day rather than a millionaire because being a mathematician is being able to discover something new each day and to explore different aspects of math. One thing that i can learn from this talk is that math is very adventurous and that learning something new each day is a wonderful thing to know.
How does The Workshop help me in future math learning?
The workshop can help me in future math learning because the workshop taught me to read the question carefully, find out what the question is asking me to and and to stick to what I am looking for, instead of making the question more complicated and harder for me. Look at the question carefully, and try different methods of solving the problem. The workshop also taught me that math can be very difficult just because of the wording, but just read the question carefully and focus on the main thing. Also it taught me not to be scared of the question and just to think about it and be determined that i can figure it out.

My Very First Blog
Set #3, Number 7
So, whats up this is my very first blog
i hope you like it :D
So for our grade 10 math class we started keeping a journal on what we have learned lately, and some recent questions that we did for class. For example, this week we did a set of math questions, this is our #3 set. One of my favourite questions for this set was question number 7:
7) In the diagram, the sum of numbers in each quarter circle is the same. The value of x+y+z is?
A) 75 B) 64 C) 54
D) 171 E) 300
The question is asking me when you add x+y+z, what is the the value of the sum.
The solution to question 7 is...........
1) I found out the sum of the first box, which is 13, 17 and 45=75
2) I add the second box (28, 8, x), which gave me 36, than subtracted 75 from 36, equals to 39. Therefore z=39
3) I then found out what the third box equals (3, y, 63), which gave me 66, and subtracted 66 from 75 again, which then equals to 9. Hence y=9
4) Then I found the sum of the fourth box (x, 19, 50), which gave me 69, than I subtracted it from 75, which equals 6. Therefore x=6
5) After finding out what x, y and z equals I added all three of them up (39+9+6), which =54
The answer is: C) 54
I liked this math equation because it was a very step by step process that was easy to understand. It gave me a visual picture in my head. I also really like this math question because when you first read the question it sounds really complicated, but after you read it a second time, you come to a realization that it's actually not that hard.
I learned that just because, at first glance it sound complicated and even though their are a lot of numbers, doesn't mean that its actually hard. I should learn to read through the question a couple of time, before i decide to skip it and go on to the next one. I also learned that just because their are a lot of number, I shouldn't be tricked by the amount of numbers in the question. I should think through the question thoroughly
