HELL NAH

So, i use Drawabox.com to study art and all was fine and dandy until lesson 6 

WHAT IS THAT NUMBERS AND WHATS HAPPENING?? IT DOESNT MAKE ANY SENSE TO ME EVEN AFTER I READ THOUGHT THE EXPLICATION?? IT DOESNT MAKE SENSE TO ME 

 mother, please pick me up i'm scared

yk what? i will just open my wings once again and find another place to study about objects and cars  ( Drawabox is armazaing but i think the whole 12812 pages for one subject isnt my thing and stuff.. also the whole math thing too )
