Easy, if the question is- Its (5-0.5)x0.22=?
You do the parenthesis first- which equals 4.5 and then multiply it by 0.22. Therefore the answer would be 0.99. So, the people who posted above me are right.
So, remember, when doing order of operations: BEDMAS.
B-Brackets
E-Exponents
D-Division
M-Multiplication
A-Adding
S-Subtraction
But, division and multiplication could be switched around, which ever comes first on the page. Same with adding and subtracting.

...right...
Anyway, it's not that simple for me anymore, 'cause I'm a C programmer. Here is
my order of operations list.
Brackets, parenthesis, members, member indirection, postincrement, postdecrement
preincrement, predecrement, sizeof, address of, pointer indirection, positive, negative, bitwise NOT, logical NOT
typecasting
Multiplication,division,division remainder
addition,subtraction
bitwise shift left, bitwise shift right
less than,greater than, less than or equal to, greater than or equal to
equal, not equal
bitwise AND
bitwise XOR
bitwise OR
logical AND
logical OR
inline conditional
assignment
sequential evaluation
Needless to say, for the most part I just use a lot of parentheiss...
