    Numbers Zero
AI Thread Summary
Numbers greater than zero are commonly referred to as positive numbers. Specifically, integers greater than zero are known as natural numbers, though the inclusion of zero in this category varies by convention. Real numbers greater than zero do not have a distinct name beyond being labeled as positive reals. The term "positive integers" is also used to describe natural numbers excluding zero. The convention regarding whether zero is considered a natural number is evolving, with many adopting the view that it is included.

Is there a name for all numbers greater than zero?
 
Mathematics news on Phys.org
You need to be more specific. If you mean the integers greater than zero, these are called the natural numbers. If you mean real numbers greater than zero, then no, there is no special name for them.
 
just the use of the adjective positive: "positve reals"

Whether or not the natural numbers contains 0 is a matter of convention.

My general impression is that the convention "0 is a natural number" is becoming standard.
 
You can also call them the "positive integers".
 
Thread 'Video on imaginary numbers and some queries'
Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
