Why do fermionic fields use Grassmann numbers?

[bengeof]

My background is QM as done in Griffiths( So yes I have a background of operators, observables and scattering matrix), Classical fields as done in Goldstein and Particle physics as in Griffiths. Griffiths actually works out Feynman rules for QED and QCD. I've started QFT with Peskin and Schroeder and Zee's QFT in a nutshell. I need help in understanding the use of Grassman numbers in fermionic fields

What is your question?

What is grassman numbers? I didn't understand the wiki article on it. . and how is it used in the quantization of fermionic fields ?

Thanks

This is far too general for us to be of much use without writing a textbook style introduction. You say you have read the Wiki page, exactly what about them did you run into problems with?
