I want to ask about arithmetical operators.

1. It is written the following:
A = B + C, with description that add A to B and assign the result to C.
Is it mistake?
The same with A = B - C.

2. And I do not understand A = A % C, with description: A is remider of division of B on C(ex: 10%2 will produce 0).
I simple do not understand 10 % 2 = 0 and 10 % 3 = 1.
May you explain? :confused:

3. It was mentioned that we can not write as:
A=(B++)*5
we must write: :confused:
A++;
B=A*5


May be the following:
B++;
A=B*5
