1. 8x8=64 What is 64?






2. Percent decrease






3. The difference between the greatest and the least numbers in a set of data.






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






5. The smallest number that is a multiple of both numbers. (the LCM of 15 and 6 is 30)

7. A number that is multiplied by another number to find a producr






8. Able to be divided evenly (without a remainder)






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






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






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






12. Rational numbers that expressed in decimal format that have fixed number of digits. 1.5 etc.






13. Rational numbers in decimal form that have a block of on or more digits that repeat continuously






14. Reciprocal of number






15. Number divisible by 6






16. When a number is larger than the other number. Example 65 > 56






17. The property which allows you to add a number's opposite to it and always get 0 - The relationship of addition to subtraction or multiplication to division






18. Percent increase






19. The smallest number in a group of numbers






20. Reducing fractions






21. A fraction out of 100 - %






22. Add up the digits; if the sum is a multiple of 3 the number is divisible by 3






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






24. To perform a calculation - E.g. 2+2=4






25. The answer to a multiplication problem

29. How much a number is worth






30. 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)=






31. 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.






32. Dividing decimals






33. 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

46. In multiplication or addition - the order of two numbers may be switched around and the answer is the same. Ex: a+b = b+a. or (1x2) x 3=1x (2x3)






47. 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)
