well anyways, i grew up always thinking that the set of numbers {0,1,2,3....} was the set of whole numbers and the set of numbers {1,2,3.....} was the set of natural numbers, so i was really confused that a prestigious board such as CAIE
(Cambridge Assessment International Education) would say something like this, this their whole statement word for word: Natural numbers
A child learns to count ‘one, two, three, four, …’. These are sometimes
called the counting numbers or whole numbers.
The child will say ‘I am three’, or ‘I live at number 73’.
If we include the number 0, then we have the set of numbers called the
natural numbers.
The set of natural numbers N = {0, 1, 2, 3, 4, …}.
so which one is right or is it a matter of choice between accepting 0 in natural numbers and not, and yeah, the book is CAIE IGCSE Math, which can't be wrong(right?), so what am i supposed to do, can i choose or do i have to go with one or the other and apart from Wikipedia and all that, what are your personal views on this.
I thought i knew what natural numbers were, numbers excluding zero and the negative numbers but my book says that natural numbers include 0, but byjus says that natural numbers dont include zero, some say they do and some say they dont and chatgpt just says, well this : The terminology around natural numbers and whole numbers can vary slightly depending on the context or educational system. In some definitions, natural numbers are defined as the positive integers starting from 1, while in others, they include 0 as well.
Traditionally, natural numbers referred to the counting numbers
1
,
2
,
3
,
4
,
…
1,2,3,4,… and did not include zero. This definition was prevalent in older mathematical literature and some educational systems.
However, in modern mathematics and many educational curricula, the term "natural numbers" often includes zero, thus encompassing the entire set of non-negative integers
0
,
1
,
2
,
3
,
…
0,1,2,3,…. This broader definition is more inclusive and aligns with the concept of natural numbers being the numbers we use for counting, starting from zero.
On the other hand, "whole numbers" are generally understood to include zero along with the positive integers. So, while there might be some variation in definitions between different sources or educational systems, it's important to understand the context in which these terms are being used. Ultimately, the distinction between natural numbers and whole numbers may vary depending on the specific curriculum or educational material being used. (Im confused help me!!).
Hello guys, I was gone for some time, but now I'm back and I'd love to soon start doing math once again.
it says to find the 27th and 34th term of the given sequence 31, -21, -11, -1, 9....
but i can't seem to find the common difference.
find the value of x^4 + 1/x^4 if the value of x + 1/x is 7
Well, i guess i just have to stick to 49.5, thanks for answering, and yeah bob it's serious global warming, this is a significant increase in temperature, but it is not enough to cause immediate death for most people. However, such a significant increase in temperature would have severe consequences for the environment and the planet, including more frequent and intense heat waves, droughts, wildfires, and other extreme weather events. It could also have negative impacts on agriculture, biodiversity, and human health, among other things. Therefore, it is important to take action to address climate change and reduce greenhouse gas emissions to prevent such a scenario from happening.
Hi Ganesh, then maybe the book was wrong, also thanks for answering.
Hi Ganesh, i also arrived to the same conclusion as you but my book say's the answer is 28 degrees Celsius, is there a flaw in mine and your calculations?
Each year, the average temperature of a region is increasing by 2.5degrees Celsius. If the average temperature recorded in 2014 was 27degrees Celsius, what will be the average temperature in the 10th year?
Thanks Bob
Alice and Bob take 2 hours to complete a task, Alice and Charlie take 3 hours to complete a task and Bob and Charlie take 4 hours to complete a task, how much time will Alice, Bob and Charlie take to complete
that same task?
how do you solve this question.
The PowerPoint joke was good.
Hi phrontister,
the answer is scenario 1 with depreciation.
Hi phrontister;
the answer is 719,512.5, look at Ganesh's post.
Thanks, a lot Ganesh
I tried using LaTeX, but it didn't work how do you use it.
Thanks, a lot.
A person insured his vehicle worth Rs. 450,000 at a rate of 2.5% for 4 years. After 3 years he got a claim of damages worth Rs. 750,000. How much loss had he recovered through insurance.
How do you solve this question?
Thanks everybody especially Bob.
I'm confused Bob says its 5.2 days and Ganesh says its 1.3 days what's the correct answer.
Bob thank you so much!!, the answer was from the option.1 method where you said work back to find markup (cost = 15600 * 100/107 then markup = cost price) and double this also this question was from
my schoolbook and thank you again for helping me.
The price of a mobile including markup is Rs 15600. If the markup rate is 7% per annum, find the amount of markup for 2 years.
What is the answer to this question please help if you can.
Thank you Ganesh.
