I hope this isnt dumb but why are we allowed to replace x with -x?

Not a huge fan of this short, honestly. Having to jump a few steps to cut the length made it pretty confusing to follow.

i hate math with a passion.. i only do basic math in my adult life.. never used advanced math ever never needed it. nothing in my life would ever require finding x.
