I agree that applying things like number theory requires extensive insight, but I do believe that i have to see a fair amount of those questions (where i solved/attempted to solve) in order to develop the skills to see through the trickeries of those questions and apply the skills
I'm currently in IB SL Math (No HL here unfortunately), and I wish to learn more about contest-type mathematics as I have 3-4 contest here this year. Is there any books/materials that's useful for me?
I have taken a look at this book: https://www.amazon.com/dp/0817645276/?tag=pfamazon01-20...
Yeah I agree. Here's another one of these type of contest question.
a^2 - 4b > 0
a + b = ?
seems very difficult.
Also from all the practise questions I've seen, that the most they'll give you is 4 var with 3 eq. Usually it's 3var with 2 eq.
Well I solved it via
since that 90 - 4c = b. 4c has to be less or equal to 90, which will make c less than 22. Include 0, so there's 23 solutions.
I'm not sure if this would be a way to solve all these types?
I've been doing some math contest stuff, and I find a lot of questions that's like 3 different variables, with 2 equations. It asks me to find the number of different possible combinations.
Here's an example:
a+b+c = 110
a+2b+5c = 200
How many different combo of abc are there? (a, b...
Homework Statement
I currently want to add 2 percent each with a relative uncertainty together:
\frac{53.3\% +/- 1\% + 65.8\% +/- 1\%}{2}
I'm not sure how I can add the percentage uncertainty.

I'm asked to draw the Lewis diagram of TeCl4.
Homework Equations
The Attempt at a Solution
As far as I understand, Te will give away 4 electrons to all the 4Cls. Since Te has 14 electrons, it leaves it with 10 electrons.
Why would i get 1 lone pair then? I'm...
