1. A whole number such as 1 - 3 - 5 and so on that cannot be evenly divisible by 2






2. A property of real numbers that states that the sum or product of a set of numbers is the same - regardless of how the numbers are grouped - (a+b)+c=a+(b+c) - e.g. (1+2)+3=1+(2+3)






3. To place a fraction in lowest terms






4. Two factors together that are multiplied to equal a larger number.






5. A shortcut for writing repeated multiplication






6. A property indicating a special way in which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses - such as a(b + c) = ab + ac - or 7x (4+1)=






7. A number with only two factors - one and itself - E.g. 3 -7 -11 -13 -17 -19...






8. 1/5 + 1/4=4/20 +5/20 and 20 is the...






9. Choosing numbers close to the numbers in a problem - and then adjusting the answer to compensate for the numbers chosen - E.g. 23 + 18 and 23+20=43 Since 2 was added to 18 to make 20 - we need to take 2 away from 43.






10. The greatest whole number that is a factor of two or more nonzero whole numbers
