Ye

The stuff i remember slowly is that a linear system of equations can have 3 solutions.
1. no solution
2. exactly one solution
3. infinite amount of solutions

yes, a linear view of the world would be nice. but theres so much crazy shit in math its unreal. If youre interested: google for the solution for the squareroot of a negative number for a little entry
