1. 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)






2. Percent increase






3. Cannot be expressed in the form a/b. Include square roots of whole numbers that are not perfect squares and non terminating decimals that do not repeat. pi






4. 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)=

6. Adding/subtracting fractions






7. A number made up of a whole number and a fraction






8. To change a percent to a decimal






9. The value of a digit based on its position within a number - e.g. 2 -432 The position of the numbers






10. The answer to a multiplication problem

12. A number that represents a part of a whole or a group; also means 'divided by' - E.g. 1/2 -3/4.5/6






13. Reducing fractions






14. Numbers that are easy to compute mentally - E.g. 34 / 5 is close to 35 / 5






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






16. Percent x whole






17. When you add 0 to a number - or mulltiply a number by 1 - the result is the same number - e.g. Identity Property of Multiplication: 21x1=1x21=21 or 300x 1 = 300






18. A line for representing and graphing numbers. Each point on the line corresponds to a number.






19. Two expressions that are set equal to each other; a number sentence with an equal sign






20. A number written in expanded form with the place values written in exponential form - E.g. 2432=2000+400+30+2






21. Median






22. Dividing fractions






23. The largest number in a group of numbers

41. New whole






42. Relationship in which a number is smaller than another






43. 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.






44. Adding/subtracting decimals
