Which is more math related stream in engineering?
Mechanical,Electrical and Civil are the branches which requires a lot of mathematical calculations and physics.While if you talk about CSE branch it involves logical thinking and statistics. Your maths should me somewhat strong to do engineering from any field.
All the best!:)

You will find maths in all the branches of engineering.
You should choose the branch according to your interest and passion.
If you have interest in Maths you can go for civil, mehanical or electrical field.
You should focus on to get top college of engineering, so, that you can get good placements.
Good luck!!
However, Computer scienece engineeeing is one such field which applies Statistics and tools and hence, Mathematics is common application of it.
Calculus,image processing, probability, Computing Numerics, Digital Binary Analysis are some few areas of expertise.
You can hence take up either Bsc Statistics or Btech Computer science if you have really good mathematical skills and number crunching ability.
You can also take up Bsc Applied Mathematics with University of Edinburgh which has amazing Placements
