Iam interested in maths subject, which branch is best for me in engineering..?
Maths is a very important tool buddy.
Since you have asked maths play a major role in computer science Engineering and electrical engineering.
Electrical Engineeringtends to use the most mathematics (Probability, Linear Algebra, Fourier Analysis, etc.)
Discrete math is sometimes referred to as the math for computer science. Topics in discrete math that are used in computer science include graphs, recursive formulas, counting, logic, probability and matrices.
So coose between CS and EEE. Which you like the most.
