Mistake, another way to say messed up. Generally a simple mistake that can or will lead to a greater error.
Associated with problems that can take a while to figure out. Including homework, research, art, anything with a
challenging and
everything in-between.
I really donked up my
homework, I thought Hydrogen had two
electrons when it really had one. I wish my teacher had pointed out my simple mistake earlier instead of handing me back my paper marked up with
highlighted errors. D:
