Atariseth: step by strep
first the a variable is 2-4= -2 =-2a
cuz itrs the same variable on both ''sides' but even with no () it would be the same
secondly the b varible is 3-5 = -2 =-2b nnnonono the negative in front of the() 'second pack is null by the negative b so - - = +
so scondly from this we got 3--5=8 remember -- gives + so its +8b
thirdly the negative right before variable dosent null with - infront of the pack meaning -c witch is in fact -1c - so -1-2 = -3 so its -3c
when last combined in order -2a +8b -3c
