---------
Use 4 scans of the problem from left to right.
1st scan: evaluate parentheses
2nd scan: apply exponents
3rd scan: multipy/divide as they occur from left to right
4th scan: add/subtract as they occur from left to right
-----------
Example:
(3-4)^2 - 4*(3/5)+(7-4)^3
------
1st scan: (-1)^2-4*(3/5)+3^2
------
2nd scan: 1-4*(3/5) + 9
------
3rd scan 1-(12/5) + 9
------
45h scan: 10-(12/5) = 38/5
Final = 7 3/5
