without order of operation answers would be all over the map. One wouldnt know which operation to perform 1st, inbetween and , lastly.
:
take this problem for instance:3%2A5-2%5E2%2B7
:
if we just perform the operations as we come to them we would get:
:
15-2%5E2%2B7=13%5E2%2B7=169%2B7=176
:
but if done in proper order the exponent would be done first followed by multiplcation and lastly(addition and subtraction)all left to right
:
3%2A5-4%2B7=15-4%2B7=18
