Answer 2

My teacher taught me this some years back.
2 lies (2 falses) make 1 big lie (false) but not a truth.

Answer 3

false && false = false
only
true && true = true

Answer 4

Let us do little maths and assign 1 to 'true' and 0 to 'false'
&& (and) operation is equivalent to the product of numbers hence
false && false = 0 X 0 = 0 = false.
Isn't simple

Answer 5

AND (&&)
-> if any is FALSE then result is FALSE
-> therefore, all must be TRUE for result to be TRUE
OR (||)
-> if any is TRUE then result is TRUE
-> all must be FALSE for result to be FALSE
NOT (!)
-> reverts the value, eg. not FALSE is TRUE and not TRUE is FALSE
Priority order of evaluation: NOT, AND, OR eg:
-> NOT FALSE || TRUE && FALSE => TRUE
-> order of eval. can be changed with "()", eg:
-> NOT (FALSE || TRUE) && FALSE => FALSE
it makes sense if you think logically, to get TRUE
-> with AND, *all* conditions must be TRUE
-> but with OR, *any* can be TRUE
maybe I'm biased by experience, i don't know, but don't worry about it, soon it will come to you as natural as 1+1.
hope it helps

Answer 6

Just to complete the previous answers: && (there're two &s here) acts as a shortcut operator, meaning that when you type a&&b, "a" is evaluated first, and if it's false, "b" is not evaluated and the whole condition is false. So strictly speaking, false&&false is false because of the first false (the one at the left of &&).
