MATH 3339 TEST 2 ACTUAL TEST PAPER
2026 QUESTIONS WITH ANSWERS GRADED
A+
⩥ Ordinal numbers. Answer: numbers that describe position or order
(first, second . . .)
⩥ Base 10. Answer: Also known as decimal system or denary system.
Each digit in a position can have a number from 0 to 9.
⩥ Whole Numbers. Answer: Natural numbers and zero (0, 1, 2, 3)
⩥ Integers. Answer: Whole numbers and their corresponding negatives
(0..-3,-2,-1,0,1,2,3...)
⩥ Natural Numbers. Answer: those numbers we typcally use to count
1,2,3
⩥ Fractions. Answer: Portions of integers, expressed with a numerator
and a denominator 1/4, 1/2, etc)
⩥ Decimals. Answer: Portions of integers, expressed as numbers
following a decimal point (0.5, 0.67, etc).
,⩥ Even Numbers. Answer: Integers divisible by two (...-6, -4, -2, 2, 4, 6)
⩥ Odd numbers. Answer: integers that are not divisible by two (...-7, -5,
-3, 3, 5 etc)
⩥ Rational Numbers. Answer: are all integers and fractions
⩥ Irrational Numbers. Answer: any numbers that cannot be expressed as
fractions, such as an infinite, non-repeating decimal
⩥ 0. Answer: The sum of a number and its additive inverse
⩥ Order of Operations. Answer: PEMDAS- Parenthesis, exponents,
Multiplication, Division, Addition, and Subtraction. Please excuse my
dear aunt sally
⩥ Step 1: Order of operations. Answer: P: Parentheses - do everything in
parentheses first. If there is more than one operation inside the
parentheses do PEMDAS order
⩥ Step 2: Order of operations. Answer: E: Exponents - deal with any
exponents next (squared)
,⩥ Step 3: Order of operations. Answer: M/D: Multiply and divide. This
can be done in the same step as one another.
⩥ Step 4: Order of operations. Answer: A/D: Addition & Subtration.
This can be done in the same step as one another.
⩥ Factors. Answer: whole numbers that are multiplied together to get a
product. Ex: The factors of 16 are 1, 2, 3, 8 & 16.
The process of breaking a # down is factoring
Whole numbers can be classified by how many factors they have as
either being prime or composite numbers
⩥ Factor tree. Answer: A diagram showing the prime factorization of a
number. The factors branch out from the previous factors until all of the
factors are PRIME NUMBERS.
⩥ Prime Number. Answer: #'s (other than 0 & 1) that have only two
factors, themselves and 1.
Ex: 2, 3, 4, 5, 7, 11...
, ⩥ Composite Numbers. Answer: any positive integers that are not prime,
meaning they have more than two factors.
4, 6, 8, 9, 10...
⩥ Greatest Common Factor (GCF). Answer: when comparing the factors
of two numbers, the largest factor they have in common is the GCF
Factors of 20: 1. 2. 4. 5. 10. 20
Factors of 24: 1.2.3.4.6.8.12.24
GCF=4
⩥ Least Common Multiple (LCM). Answer: when comparing the
multiples of two numbers, the smallest multiple they have in common is
the LCM
Multiples of 3: 3,6,9,12,15, 18, 21
Multiples of 5: 5,10, 15, 20,
LCM=15
