Operator Precedence


For example, suppose you have the statement 

x = 6 * 5 / 2 - 5 + 11

In normal circumstances, the variable x would be evaluated in the following order: 

6*5=30
30/2=15
15-5=10
10+11=21
x=21 'Final value of X

If you want to express 5+11 the first, just surround them with parentheses: 

x = 6 * 5 / 2 - ( 5 + 11 )

which would result in the following order: 

5+11=16
6*5=30
30/2=15
15-16=-1
x=-1 'Final value of X

The difference in results is due to the parentheses around part of the expression, which can have a dramatic impact on the results.
