[Questions 1-20] [Questions 21-40] [Questions 41-60] [Questions 61-80]
For those of you who would prefer to view the methods and tricks according to their placement on the test, this page is for you. Of course, this is just an estimate. I do not know exactly where some of these tricks occur so this page is based on my guesses.
The placements on this page are based on high school number sense tests.
Before looking at these methods, be sure you know all the basic memorizations here.
