| 1
|
A
widely used floating-point system in which numbers are
expressed as products consisting of a number between 1 and 10
multiplied by an appropriate power of 10, (i.e. 562 = 5.62
times 10 squared) |
| 4
|
A
number (as 1, 5, 15) that is used in simple counting and that
indicates how many elements there are in a set. |
| 5
|
Any
real number expressed in base 10 notation, such as
2.673 |
| 6
|
A
number that cannot be expressed as a quotient of two integers,
i.e. the square root of 2. It can be shown that a number is
irrational if and only if it cannot be written as a repeating
or terminating decimal. |
| 8
|
A
number that can be written as the ratio of an integer to a
counting number; or more formally, a number that can be
expressed as a ratio a/b where a and b are integers and b is
not equal to zero, i.e., 0.5, 3/5, -3, 8 |
| 9
|
A
number designating the place (as first, second, or third)
occupied by an item in an ordered sequence. |
| 10
|
The
number that indicates how many times the base is used as a
factor. |
| 11
|
A
number from the set of numbers consisting of all rational and
all irrational numbers. |
| 12
|
A
number that can be written in the form a + bi where a and b
are real numbers and i = the square root of -1. |
| 13
|
A
set of elements ordered so that they can be labeled with
consecutive positive integers starting with 1, for example 1,
3, 9, 27, 81. | |
| Down: |
| 2
|
A
number that is either a whole number or the negative of a
whole number. |
| 3
|
1.
do all the operations inside parentheses, and/or above and
below a fraction bar in the proper order. 2. Find the value of
any powers or roots, 3. Multiply and divide from left to
right, 4. Add and subtract from left to right. |
| 7
|
A
number that is neither a counting number or
zero. | |
