The numbers under a QR code typically represent the encoded data, which can include URLs, text, or other information. These numbers are part of the QR code's structure, helping to identify and retrieve the data when scanned by a QR code reader. The specific arrangement of the numbers and patterns within the code allows the reader to accurately decode the information.

Why is the multiplication of rational numbers always result in a rational number?
It follows from the closure of integers under addition and multiplication.Any rational number can be expressed as a ratio of two integers, where the second is not zero. So two rational numbers may be expressed as p/q and r/s.A common multiple of their denominators is qs. So the numbers could also have been expressed as ps/qs and qr/qs.Both these have the same denominator so their sum is (ps + qr)/qs.Now, because the set of integers is closed under multiplication, ps, qr and qs are integers and because the set of integers is closed under addition, ps + qr is an integer.Thus the sum has been expressed as a ratio of two integers, ps + qr, and qs and so it is a rational number.
Why is the difference between two rational numbers always a rational number?
Suppose x and y are two rational numbers. Therefore x = p/q and y = r/s where p, q, r and s are integers and q and s are not zero.Then x - y = p/q - r/s = ps/qs - qr/qs = (ps - qr)/qsBy the closure of the set of integers under multiplication, ps, qr and qs are all integers,by the closure of the set of integers under subtraction, (ps - qr) is an integer,and by the multiplicative properties of 0, qs is non zero.Therefore (ps - qr)/qs satisfies the requirements of a rational number.
Who invented the QR code?
The QR code was invented in 1994 by a Japanese company called Denso Wave, which is a subsidiary of the Toyota Group. The code was developed by Masahiro Hara and his team to improve the tracking of automotive parts during manufacturing. Unlike traditional barcodes, QR codes can store more information and can be scanned at high speeds, making them more versatile for various applications.
