Question 36163
 3+4-20/5*2


You have to do multiplications and divisions first in this problem,but most importantly, because mult and division are on the SAME level of operation, you must do it from LEFT to RIGHT.  This means that in this case, you must divide first, and then multiply!!  

3+4 - 4*2


Next, do additions and subtractions, again from LEFT to RIGHT!!
3+4 - 8
