The order of computation for the above expression is:
1.Calculate e - f. e-f
2.Calculate C * d. c * d
3.Divide C * d by e - f. (c * d) / (e - f)
4.Add the above result to b. b + (c * d) / (e - f)
5.Subtract g from the above result. (b + (c * d) / (e - f)) - g

Explanation of grouping convention:
Left to right ... 1 + 2 - 3 is interpreted as (1 + 2) - 3.
Right to left ... NOT-3 is interpreted as NOT (-3).
