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.

If using a smartphone to scan and read qr code symbols, a qr code reader app must be installed on the smartphone. There are a lot of such apps for both iOS and Android available. Smartphone uses the camera as the scanner to read the qr symbols. See the related link for a qr code library for creating qr code generator on Android.
How do you create a QR code for your website?
A QR code is generated by a special software program developed for that purpose. Fortunately, these "QR code generators" are free online from various sources. You simply enter your URL or website address and a graphic QR code will appear on the screen. You then save that file to your computer where you can then print it onto anything you want. The standard QR code generated for free will be a square bar-code in black and white. However, that code can be further customized using graphics programs so that it fits better with your logo or website. There are discussions about how to customize QR codes.
