NOTE:
•
#1: All arithmetic involves ‘signed’ numbers. That is, negative and positive numbers.
•
#2: A calculator (or cell phone, or translator or any similar device) is NEVER allowed.
•
#3: All fractions must be completely simplified.
•
#4: The problems on the ‘Samples’ exam contains problems similar to, but not exactly like, problems on the actual Challenge Exam. Further, the Challenge Exam may contain problems that are not shown on the ‘Samples’
Exam.’ STUDY !!
