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






9. Answer to a division problem






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






11. 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






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






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

22. New whole






23. 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.
