Answer 2

Yes. You are correct, but this was not the case.

Answer 3

First is equivalent with sum = sum + (variable). This means that the value of sum is increased by the value of (variable)

Second is equivalent with sum = (variable). This means that the value of sum becomes the value of (variable)

Answer 4

Gabriel Ilie, Hi! why do you put the "nr" variable in brackets in your code example?

Answer 5

No reason. Just to note that the brackets have no impact in the result

Answer 6

in some cases, parentheses have a value. in them, the expression is evaluated first

Answer 7

maybe in this question the second part of the example refers to the use of the unary plus? that is, if a negative value is stored in a variable, then plus converts it to a positive value
