10. Percent increase






11. Average value






12. 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.






13. Number divisible by 2






14. To drop a percent






15. In 4x4=16 - what is 4?






16. To place a fraction in lowest terms

18. The number at the top of a fraction; stands for the parts of a set you are considering - E.g. 3/4 What position is 3?
