What symbol would you use to indicate that a number is a label and not a value?
Write an apostrophe ( ' ) in the cell, before the number.
How is negative two greater than zero?
The underlying supposition, namely that -2 > 0, is incorrect. 0 is a more positive quantity than -2 and would be considered "larger". The only way that -2 would be considered "greater" than 0 is if the numbers are being evaluated for their magnitude or absolute value. Since the magnitude or absolute value of a number is the same number but with a positive sign in all cases, |-2| IS > 0 because 2 > 0.
What is the order of magnitude for the number of great lakes?
There are 5 great lakes. The order of magnitude of the number 5 is 0. Order of magnitude is determined by powers of 10. So, 150 would be order of magnitude of 2, since you could write 150 as 1.5 * 102. Similarly, 5 can be written as 5 * 100, so the order of magnitude is 0.
Is the absolute value of a negative number is always positive?
Yes. An absolute value is just that- the ultimate magnitude of a number, the number's distance from zero. Since distance is always positive, absolute value is always positive.
Which number is an improper fraction?
An improper fraction is one in which the magnitude of the numerator (number on top) is greater than the magnitude of the denominator (number on bottom) I used the word magnitude so you wouldn't be confused by negative numbers, example: -3 -- would be improper, since 3 is greater than 2. 2
