Is maths permissible inline with 'If...Then' statements?

[mkstevo]

Is it possible to check for a range of values using something like:

If (Value > (MidValue - 10)) and (Value < (MidValue + 10)) Then
...
End If

Assuming it is, would I need to encase my test statements in brackets as the above example, or the example below:

If Value > (MidValue - 10) and Value < (MidValue + 10) Then
...
End If

Or would I need to do the maths prior to the 'If...Then' as this:

Let LoValue = MidValue - 10
Let HiValue = MidValue + 10
If Value > LoValue and Value < HiValue Then
...
End If

Always play safe.

LoValue = MidValue - 10
HiValue = MidValue + 10
If Value > LoValue and Value < HiValue Then
...
End If

and, no need for LET statements.

Thanks for the reply.

While 'Let' statement is not required in CGB, I find it helps me to focus. I see the 'Let' statement and understand that it is a value assignment, as opposed to a test of equality. It is perhaps a hangover from my Delphi (Object Pascal) time where the symbol for a test of equality was '=' and the symbol for a value assignment was ':='.
