# Suggest me some textbooks please~!

I have so much trouble in these topics, especially algebra. (even though I'm lvl 5):

Algebra

• Linear algebra
• Proving inequalities (every single theorem)
• Polynomials, functional equations and analysis
• Trigonometry and complex numbers (from basic to advanced)
• Sequences and series

Combinatorics

• Pigeonhole principle (my brain is like a pigeon in this topic)
• Colouring techniques
• Generating functions

Geometry

• Trilinear coordinates and barycentric coordinates
• Triangle centers
• Special stuffs of a triangle (Pedal triangle, 9-point circle, etc)

Number Theory

• Modular arithmetic (especially Chinese Remainder Theorem)

I'm starting to do some coding and stuffs, can you suggest me which coding language is easier, and what website I can learn coding?

Thank you!

I can recommend codecademy for programming. The best way to learn programming is by doing it.

better than Khan Academy's programming? I mean, all I've learned in first two hours is how to move a rectangles and ellipses and color them and stuff

i agree with you @John Muradeli khan programming is not the best
