ABCTE-MSE-MATH/NUMBERS EXAM
QUESTIONS & ANSWERS
real numbers - Correct Answers -the set of all rational and irrational numbers.
Essentially, they are all the numbers on a number line.
rational numbers - Correct Answers -numbers that can be written as a fraction a/b,
where a and b are integers and .b does not = 0
- fractions, repeating decimals, and terminating decimals
For example: 3/5; 5; -27; -4/17; ; 4.7623
irrational numbers - Correct Answers -numbers that cannot be written as a fraction a/b,
where a and b are integers and . they become decimals that do not terminate or repeat.
Nonperfect square roots and pi are the most commonly used.
whole numbers - Correct Answers -the counting numbers, starting with zero.
For example: 0, 1, 2, 3, 4, 5, 6, . . .
integers - Correct Answers -the positive and negative counting numbers, including zero.
For example: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 . . .
commutative property - Correct Answers -The ORDER of two numbers may be switched
around and the answer is the same. Order is not important when adding or multiplying
numbers 4+7=7+4
prime factorization - Correct Answers -the process that finds the prime-number products
of a given composite number.
ratio - Correct Answers -quotient used to compare two numbers
proportion - Correct Answers -two or more ratios that are equivalent to each other. ths
cross products are equal
Associative property - Correct Answers -The GROUPING is not important when adding
or multiplying numbers. 3+(4+7)=
Identity Property - Correct Answers -The number wants to be the same- to be itSELF.
4+0=4, 8X1=8
Multiplicative property of 0 - Correct Answers -any number times zero is zero
