false
False
When you add them, you always get an even number; when you multiply them, the result is always odd.
You don't say
False. Supplementary angles add to 180degrees.
False. The statement is not true if either of the numbers is 0 or negative.
false
False
yes

True the 3 interior angles of any triangle always add up to 180 degrees
No because if you add 5+1=6 and 6 is an even number. So it is false.
TRUE has the value of 1 and FALSE has the value of 0. So if you are only getting TRUE and FALSE results, you can add them directly, like you would any numbers. If as a result of your functions you are getting other numbers, like you could from an IF function, then you can add those values with standard methods too.
True AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True
You don't say
False. Supplementary angles add to 180degrees.
Yes. If all the question's parts are true, then the answer is true. If all the question's parts are false, then the answer is false. If one of the question's parts is false and the rest true, then the answer is false. Logically, this is illustrated below using: A = True, B = True, C = True, D = False, E = False, F = False A and B and C = True D and E and F = False A and B and D = False If you add NOT, it's a bit more complicated. A and NOT(D) = True and True = True NOT(D) and D = True and False = False NOT(A) and NOT(B) = False and False = False Using OR adds another layer of complexity. A OR NOT(E) = True OR True = True NOT(D) OR D = True OR False = False NOT(A) OR NOT(B) = False OR False = False Logic is easy once you understand the rules.
