1) "Whole numbers" can mean: non-negative integers, positive integers or all integers. "Natural numbers" can mean: non-negative integers or positive integers. So the answer would be any negative integer, or, any negative whole number. 2) The decimal of an irrational number will not terminate, there will be an infinite number of decimal places which will go on forever. eg. sqrt2 = 1.41421356.... (number goes on) pi = 3.141592653....... The decimal of a rational number will either terminate or repeat. eg. 5/9 = 0.555555555... 9/7 = 1.285714 285714 285714... 9/8 = 1.125 Rational numbers can be written as fractions. 3) True 11) Adding zero to any number will leave it unchanged 12) Adding any numbers: a + b + c can be done by: adding "a" and "b", then adding "c" to this result. adding "a" and "c", then adding "b" to this result. adding "b" and "c", then adding "a" to this result. 13) Same as above but with multiplication instead of addition 14) Multiplication can be done in any order: eg. 5 x 3 = 3 x 5 a x b = b x a 15) Multiplying and number by 1 will leave it unchanged eg. 5 x 1 = 5 a x 1 = a 16) I learned order of operations with BIDMAS: Brackets (parentheses) Indicies (exponents?) Division and; Multiplication Addition and; Subtraction So "a" is the answer. 34) x - 19 = 36 x = 36 + 19 x = 55 35) m + 27 = 78 m = 78 - 27 m = 51 36) 8 = a + 5.3 8 - 5.3 = a 2.7 = a 38) 156 = 12b 156/12 = b 13 = b 39) -9x = 108 x = 108/(-9) x = -12

Remember the order of operations: (1) Parentheses (2) Exponents (3) Multiply and Divide (4) Add and Subtract ("Please Excuse My Dear Aunt Sally" is the mnemonic often used to remember it) Remember, you also go left-to-right when evaluating expressions. Also, when looking at a fraction with an expression either in the numerator or denominator (as opposed to just a number), it is as though that expression is in parentheses. Here are the answers I came up with. 1. 121 2. 512 (8*8*8=8^3) 3. 625 4. 20 5. 63 6. 33 7. 4(8) - 5 * 4 = 32 - 20 = 12 8. 9 9. 48 10. 21 11. 62 12. 3 13. 1 14. 26 15. 1/2 or 0.5 16. 137 17. 89 18. 168 19. 50 20. 8 21. 96 22. 39 23. 5 24. -2 25. 7

1-15 are simple, and all you need is a calculator. the rest are simple and all you need is to plug in the numbers given, a = 12, b= 9, c= 4

Can you use a calculator, or do you have to show your work? It's REALLY easy with a calculator. For example, for number 2, just type into the calculator "100 x 25 %." Your calculator should have a "%" key. The answer is 25 by the way. For number 4, type in "1000 x 62 %" (the answer is 620). If you don't have a calculator handy, there is one on the computer--in Windows it is under "accessories." If nothing else, this should at least enable you to check your work. I hope this helps. You can do it, trust me!!!!

Consider doing your homework yourself. This is ridiculous. You are not going to improve any bit otherwise.
