This did not work for characters not in the Windows Code Page (such as box-drawing characters). The new Alt+0### combination (which prefixes a zero to each Alt code), produces characters from the newer "Windows code pages." [a] For example, Alt+ 0 1 6 3 yields the character £ (symbol for the pound sterling) which is at 163 in CP1252. [2] [b]
The two square roots of a negative number are both imaginary numbers, and the square root symbol refers to the principal square root, the one with a positive imaginary part. For the definition of the principal square root of other complex numbers, see Square root § Principal square root of a complex number.
The square root of a positive integer is the product of the roots of its prime factors, because the square root of a product is the product of the square roots of the factors. Since p 2 k = p k , {\textstyle {\sqrt {p^{2k}}}=p^{k},} only roots of those primes having an odd power in the factorization are necessary.

Even though this is usually not indicated on the physical keyboard—potentially due to a lack of space, since the ß-key already has three different levels (ß → "ß", ⇧ Shift+ß → "?", and, as shown above, AltGr+ß → "\")—, it can be seen in the Windows On-Screen Keyboard by selecting the necessary keys with the German keyboard ...
Many keyboards do not label AltGr as such, leaving the Alt marking as in the US layout – the right Alt key nevertheless functions as AltGr in this layout, causing possible confusion when keyboard shortcuts with the Alt key are required (these usually work only with the left Alt) and causing the key to be commonly referred to as right Alt ...

A method analogous to piece-wise linear approximation but using only arithmetic instead of algebraic equations, uses the multiplication tables in reverse: the square root of a number between 1 and 100 is between 1 and 10, so if we know 25 is a perfect square (5 × 5), and 36 is a perfect square (6 × 6), then the square root of a number greater than or equal to 25 but less than 36, begins with ...
