Your least favourite math topic

[iamito]

Hello everyone,

I thought it would be interesting to have a compilation and ranking of people's least favourite math topics in the GMAT.

By having this benchmark, beginners can have a better idea of which math topics are usually seen as more challenging.

So, if you want to give your contribution, pls list your 3 least favourite math topics.

Here's my contribution (with 1 as least favourite):
1 - Permutations and Combinations
2 - Sets (Venn diagrams)
3 - Exponents (number theory)

For your reference, here are some other math topics:
- Least Common Multiples (number theory)
- Work Problems (word problems)
- Distance/Speed Problems (word problems)
- Special Triangles (geometry)
- Areas and Volumes (geometry)
- Number Series (arithmetics)
- Even/Odd Numbers (number theory)
- Graphical representation of equations
...

I'll do a ranking of all the LFM topics once(if) we have a sufficiently large sample of answers.

Thanks!
