Where can I find a code for Deep Learning Neural Network model that has all mathematical calculations implemented?

Question

I have a project idea, I know how NN works, I had created very simple projects earlier. Since I don't know calculus and all that kind of a maths required to completely understand NN's, I don't want to bother learning all them, because I don't even know that the project I'm up to create would work or not. So, I just need a mathematically implemented multi-layered NN, where I can set the amount of hidden, input and output layers there will be. Inputs are just going to be float numbers as well as the output. I couldn't find any online, I guess I didn't know what to search for in my case.

I know, that is not actually a question. Maybe we could think this as somewhat a place for Deep Learning resource so that other people searching for such a thing can also benefit.

edit: What I need is just a deep nn model with feedforward and backpropagation methods are properly implemented that works fine with any size of layers.

Answer 1

tensorflow perhaps.

Answer 2

Logomonic Learning thanks for the answer.
I checked it out but I couldn't actually get a word. Tensorflow is for the ones who wanna do it the way these things are actually done. It has all the stuff, transposing (reshape), creating a variable called tensor so and so. I just need a simple backpropagation algorithm yet working fine with multi hidden layers. Like I said, since I don't know whether or not the project I have in my mind would work, I don't want to waste my time.
