No. I did the problem under a minute
yes because i was applying PEMDAS to this problem and this problem only.
no.
PEMDAS in general for the more layered expressions takes to long, even with a calculator, to get a simple number.
taking 30 seconds for that is too long if you ask me.
however, other stuff like long division is an exception.
just throwing this out there, i really don't understand why public schools feel the need to cram this mathematical gibberish into our heads, knowing that half of it will never be used in real life situations.
not even bankers and accountants do this kind of stuff.
seriously what happened to just doing 2+2 or $5.89 + $20.45
