MHB Value of x After Logic & Math Task w/ x=2

[vb14]

Hi Folks,
I am stack with following task:What is the value of x after each of these statements is encountered in a
computer program if x=2 before the statement is reached?

(i) if (6+2=9) then x:=x+1 .
(ii) if ((3+2=5) OR (2+3=3))then x:=x+1 .
(iii) if ((12+4=17) AND (4+5=9)) then x:=x+1.

Note 1 OR is ∨ AND is ^
Note 2 := is an assignment sign.Any help will be appreciated.
Thanks.

Is the IF part of i) true?
Is the IF part of ii) true?
Is the IF part of iii) true?

Is the IF part of i) true?
Is the IF part of ii) true?
Is the IF part of iii) true?

(i) false
(ii) false
(III) false

 

[Ackbach]

(i) false
(ii) false
(III) false

(ii) is incorrect. The first part of the OR is true, making the entire OR true. So, which THEN parts will execute?
