Answer 1

Real no

Answer 2

Imaginary

Answer 3

not natural

Answer 4

Ishaan94, whole numbers include 0, natural numbers do not.

Answer 5

how many numbers are between 1 and 2? how would you classify the numbers?

Answer 6

yea.....but u said natural not Ishaan

Answer 7

thr r infinite no.s between 1 and 2

Answer 8

i thought he said zero can be classified

sorry reading error it is can't

Answer 9

0 is an integer

Answer 10

pk is right

Answer 11

Im a girl thank u

Answer 12

lol whats to do with girl

Answer 13

maths is maths

Answer 14

okokokokok....so is 0 in natural no.s or not? I know it is not..

Answer 15

is every whole number an integer? is every integer a whole number?

Answer 16

it's not natural number you right angela

Answer 17

kk thnx :)

Answer 18

but the question is

"zero can't be classified as wich type of number"...

Answer 19

can anyone answer me question

Answer 20

:O:O:O:O:O:O:O OMG!!! oops :S :$:$:$

Answer 21

pk did that right what kinda answer your expecting

Answer 22

Integers are whole numbers, so yes @carrie

Answer 23

natural for sure

Answer 24

I asked is every whole number an integer? is every integer a whole number?

Answer 25

Thax

Answer 26

whole numbers are always positive,1,2,3,4.....etc
but integers can be positive or negative ......-1,-2,-3,0,1,2,3....

Answer 27

if the number is negative, which of the following statement is false?
1,The opposite number is to the left of zero 2. The number is to the left of zer 3, the absolute value of the number is to the right of zero.

Answer 28

so the answer of ur 1st question is YES,2nd is NO

Answer 29

it just depends on how you define these sets of numbers. I consider a whole number to be a number that doesnt have a fractional part. So in that sense, -5, -3, etc are whole numbers. If you were taught they had to be positive as well, then I see why you would disagree, and thats cool.

@carrie if the number os negative, then it is to the left of 0:
...-3, -2, -1, 0, 1, 2, 3...

Answer 30

1

Answer 31

List all the number sets that contain the number 15

Answer 32

is it true that all numbers belong to the set of complex numbers?

Answer 33

no.real numbers are not definitely.

Answer 34

yes, real numbers are also complex numbers. They are complex numbers in the form
a+bi with b = 0.

Answer 35

you have to allow real numbers to be complex numbers so the set of complex numbers can remain closed under multiplication and addition.

If a set isnt closed under those opperations, its not a Field, and it cant have inverses. Which is disastrous!

Answer 36

some more explanation please joemath.

Answer 37

yeah me too

Answer 38

So, a Field is a set of numbers (or objects) that satisfy a couple of properties.

One of the properties is called "Closure under Addition/Multiplication"

A set is closed under addition if you can pick any two elements in the set, add them, and you still remain in the set.

For example:

The set of Natural Numbers is closed under addition
{1,2,3,4....}
If i add any two natural numbers, i will still have a natural number.
The set {-1,0,1} is not closed under addition.
If i pick 1 + 1 i get 2, which isnt in the set.

Closure under multiplication means the same thing, only with multiplication.
(still more to come lol)

Answer 39

Now, if you say that Real numbers arent complex, then that would force complex numbers not to be closed under addition.

a+bi is complex, a-bi is complex, if you add them you get 2a, which (if real numbers weren't complex as well) would not be complex.

Also, we know that:
\[(a+bi)(a-bi) = a^2+b^2\]
which also wouldnt be complex

If there wasnt closure under multiplication, there wouldnt be solutions to:
\[cx = d\]

in the complex plane.

Answer 40

i understand.thanks

Answer 41

ahh I didb;t knew things go like this...this is interesting ...thanks joe

Answer 42

no prob :) i learned the formal definitions last year lol. It was a lot to grasp, but it helps.
