VERBAL IF-THEN'S For each of the following, do your best to figure out if the statement is true or false. Give an explanation (or argument) justifying why you think what you think. NOTE: Each of the following refers to "a number" or “numbers". They are general statements. So, if there is any number (or numbers) for which it's false, then the statement is false. In other words, if you are thinking "that's true in some cases (or perhaps even many cases), but it's not true in all cases," then the statement is false. Warning: The word "number" does not mean "integer" or "positive integer". All integers are numbers, but not all numbers are integers. Integers are numbers like -13, -4, 0, 27, and 132. Non-integers are numbers like 2.61, - 5.8, and 55/9. The first of these is between the consecutive integers 2 and 3. The second is between -6 and -5. The third is between 6 and 7. So if you are going to test the statements by choosing a number or numbers to test it with, do not limit yourself to…
