ABCTE-MSE-MATH/Numbers Exam
Questions And Answers (Guaranteed A+)
Real numbers - Answer✔the set of all rational and irrational numbers. Essentially, they are all
the numbers on a number line.
rational numbers - Answer✔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 - Answer✔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 - Answer✔the counting numbers, starting with zero.
For example: 0, 1, 2, 3, 4, 5, 6, . . .
integers - Answer✔the positive and negative counting numbers, including zero.
For example: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 . . .
commutative property - Answer✔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
Associative property - Answer✔The GROUPING is not important when adding or multiplying
numbers. 3+(4+7)=
Identity Property - Answer✔The number wants to be the same- to be itSELF. 4+0=4, 8X1=8
Multiplicative property of 0 - Answer✔any number times zero is zero
distributive property - Answer✔combines together addition (or subtraction) and multiplication.
The idea is that it doesn't matter if you find the product of the sum/difference or the
sum/difference of the product. a(b+c)=ab+ac and a(b-c)=ab-ac
Expression - Answer✔In mathematics, a symbol (or combination of symbols) that represents a
quantity.
