Question

Indicate whether the following statements are True (T) or False (F).

1. Sqrt of 49 is a rational number
2. Pi is a real number
3. 0 is a natural number
4. -17 is an integer
5. 3/2 is an integer
6. Sqrt of 3 is a rational number
7. 2 is a real number

If you can help that would be great!

Answer 1

first off do you know what real and natural numbers are?

Answer 2

no what is the difference

Answer 3

Natural is the way little kids naturally count

1,2,3,4,5,6 ...

Answer 4

(1) is true sqrt(49)=7 is a ration number
(2) pi is a real number. if it were pi*sqrt(-1) then is would be not real
(3) natural numbers are counting numbers when you count you start with 1 not 0 so 0 is not a natural number
(4) -17 is an integer just like 0 and 4 are
(5) 3/2 is a rational since it is an integer/integer so 3/2 is not an integer
(6) sqrt(3) is irrational because it goes on forever
(7) 2 is a real number

Answer 5

0 is a natural number

Answer 6

natural numbers denote non negative integers

Answer 7

no it is a whole number

Answer 8

not a natural number

Answer 9

The term "natural number" refers either to a member of the set of positive integers 1, 2, 3, ... (Sloane's A000027) or to the set of nonnegative integers 0, 1, 2, 3, ... (Sloane's A001477; e.g., Bourbaki 1968, Halmos 1974). Regrettably, there seems to be no general agreement about whether to include 0 in the set of natural numbers. In fact, Ribenboim (1996) states "Let be a set of natural numbers; whenever convenient, it may be assumed that ."

Answer 10

I learned that the natural numbers was also the counting set you do not start counting with 0 you start counting with 1 so 0 is not a natural

Answer 11

nerd warS!

Answer 12

Ok thanks guys, that makes sense!

Answer 13

i think for all practical purposes it doesn matter at all, any applications in advanced mathematics this becomes obselete anyway

Answer 14

not linear algebra

Answer 15

Cmon, lets be rational :D

Answer 16

sets are talked about in advanced math like linear algebra and discrete math

Answer 17

no lets be irrational

Answer 18

i took both courses and you dont care about it lol

Answer 19

we did care about it lol

Answer 20

yes for engineering its dramatically important to know if 0 is a natural number

Answer 21

lol

Answer 22

i think you are in the imaginary set

Answer 23

i doubt you took a course on this beyond high school

Answer 24

come on talk to me in a mathy way or nerdy way thats not a fun insult

Answer 25

you could had least said your mom goes to college

Answer 26

Cmon this is getting divergent. We need to integrate more. There should be a limit so stop it

Answer 27

lol

Answer 28

i like xavier

Answer 29

i think you guys just look up math facts on wikipedia.......without actual background

Answer 30

your line is tangent to the curve of bullpellet

Answer 31

Sigh...

Answer 32

please don't get offended. I was just thinking of something cool to say

Answer 33

no im not offended i just think that if you wanna go out in the real world correcting people like you do on this site ppl with the background, like me, will laugh at you because there is so much more to math then these "mathy" "nerdy" lines you are whipping out lool

Answer 34

listen i do have a mathematical background and not one of my instructors ever said 0 was in the set of the naturals

Answer 35

ok does anyone care if it is or not?

Answer 36

and you are the one who was trying to correct me

Answer 37

no i just give you an outside opinion

Answer 38

an i was giving my opinion

Answer 39

my point was that it practically doesnt matter at all, and you went on to say not if you take linear algebra

Answer 40

avalanche is was jk with you about the nerd wars I thought u were too

Answer 41

ok lol lets just calm down cuz i think this really doesn matter anyway lol

Answer 42

no i was saying they discuss sets in linear algebra

Answer 43

yes they discuss sets, for about 2 minutes

Answer 44

ok i wasn't saying your math was crap

Answer 45

ok ok ok lets calm downn lol

Answer 46

i was just looking for a friendly war :( and you hate me thats not fair

Answer 47

omg haha i dont hate you at all

Answer 48

how could you hate over text chat

Answer 49

some kind of math terrorist

Answer 50

u hate my text chat

Answer 51

? lmao

Answer 52

conclusion to anyone who reads this noone gives a sh*t if 0 is included in the natural numbers or not, if you are anything except mathematician you will most likely be able to live without arguing about it. and we are all friends

Answer 53

lol i have a masters in math and I'm fixing to get into a phd program for applied scinece

Answer 54

science*

Answer 55

..no wonder you care, see im in engineering and im more concerned with more practical things vs theory

Answer 56

lol

Answer 57

well my instructors drill it into my brain

Answer 58

not to say what ur doing isnt good

Answer 59

i could never do a masters in math thats awesome

Answer 60

it was stressful as i'm sure any degree would be

Answer 61

engineering is cool too

Answer 62

i had to take 3 calculus, stats, differential equations, linear algebra

Answer 63

i wish i didn't something with "appliedness"

Answer 64

did*

Answer 65

well depends on what you like

Answer 66

i'm going to get into a little cryptography. i cant wait

Answer 67

some stuff in engineering is far from being apploed

Answer 68

that almost sounds like computer science course of some sort

Answer 69

yes. it is applied number theory and maybe some other small topics in math and topics in computer science of course

Answer 70

i was in cs my first semester of university and decided that i couldn take 15 hour assignments in front of the computer anymore

Answer 71

but yes some topics are really interesting and might take some electives

Answer 72

i just want to look at the theory and develop my own cryptosystem

Answer 73

yea see i admire people who can learn that cuz some topics in math i look at them and unless i can think of something practically related to it i get bored, like some techniques to solve differentail equations were a bit abstract as well as 1 or 2 things in calculus

Answer 74

it was nice talking to you. I will be your fan. I have to go to sleep

Answer 75

Gnight

Answer 76

oh i was already a fan nvm
