Curry in Haskell

So today I am going to go through the function curry in Haskell. I am finding a hard time trying to understand it and this is my way of trying to understanding it.

First the type signature

This is what I get when I type in :t curry

curry :: ((a, b) -> c) -> a -> b -> c

// We will be doing animation in OpenGL
// key concepts are:
// 1. the idle function - idle() will post a replaint and this will lead to activation of the display() function
// 2. Also we will be doing double buffering like this: glutInitDisplayMode(GLUT_DOUBLE);
// In addition we will be introducing other functions such as glPushMatrix, glPopMatrix and glSwapBuffers
