Assalam o allaikum

I am a student of economics. Most of the economics that we learn is full of mathematics. The most used mathematical subjects used in economics include, real analysis, linear algebra, vector calculus, derivatives and integrals and differential calculus.

So if you can give me the names of some good authors on the above subjects, which are not that complicated as i am not that much into mathematics. Please also advice me about a dictionary of mathematics, which is easily comprehendible by a non mathematician.
