Whole Number - "whole" numbers are numbers whose values are "whole," such as 1
or 2.
Whole numbers only
not negative
not decimal
not fraction
Integers - Integers like whole numbers, are numerical figures that do not contain a
fractional or decimal component.
positive number* or a negative number*.
Whole numbers are positive integers
Rational Number - Rational numbers* are numbers that can be expressed as a fraction.
This class of numbers includes all integers since any integer can be expressed as a fraction:
.675 is a rational number because it is a decimal whose expansion ends
Fractions
Can be integers and whole numbers.
Real Numbers - A real number is any number that can be placed on the number line,
whether that be negative or positive, fraction or decimal.
, Real numbers also include decimals that do not end and cannot be written as a fraction. An
example of this is pi
are also whole numbers, integers, and rational numbers
Negative Integer - -7, -11, -986581 are examples
Positive Integer - 7 is a positive integer
True or False? Any integer is also a whole number - False
An integer can be negative, such as the number -100. -100 is not a whole number.
Read all the options before answering. -17 is...
a. an integer
b. a rational number
c. a real number - -17 is an integer, and all integers are also rational numbers, which in
turn are real numbers.
According to the strictest definition, 0.07 is... - 0.07 is a fully-expressed decimal and
therefore a rational number because it can be written as a fraction
π is... - π is a real number whose complete decimal expansion goes on forever and does
not repeat.
According to the strictest definition, fraction begin. numerator: -1/3 is. - According to
the strictest definition, fraction begin. numerator: -1denominator: 3fraction end. is a rational
number because it can be represented as a fraction.
Relative Value - 8>5. Where a number falls on the number line
6 ÷ 0 = undefined - when we divide an integer by zero, the answer is always
"undefined." Whether positive or negative, an integer divided by zero will deliver an
"undefined" result.
Exponents - Sometimes called power, it is the number that shows how many times the
base is multiplied by itself
