Answer:
okay so PEMDAS
P=parenthesis. There isnt anything in a parenthesis, the parenthesis here are for multiplication.
E=exponents. no exponents.
M=multiplication. we have that so do that first.
5(9) and 70(6) that equals 45 and 420. now the equation is
45 + 420 - 79 + 31 + 1 - 210 - 208
D=Division. no division
A=Addition
S=subtraction. there is both. go left to right.
45 + 420 =465. now the equation is 465 - 79 + 31 + 1 - 210 - 208
465 - 79 = 386. now the equation is 386 + 31 + 1 - 210 - 208
386 + 31 = 417. now the equation is 417 + 1 - 210 - 208
417 + 1 = 418. now the equation is 418 - 210 - 208
418 - 210 = 208. now the equation is 208 - 208
208 - 208 = 0. Therefore 5(9) + 70(6) - 79 + 31 + 1 - 210 - 208 = 0
