You should say "zero" as the number name, but it's common and acceptable in spoken English (especially for phone numbers, dates, and addresses) to say "oh" for the digit 0 for convenience; however, use "zero" when precision is crucial, like in technical codes, to avoid confusion with the letter "O".
Practical rule of thumb: use ``O'' or ``oh'' in informal strings (phone numbers, years, casual addresses); use ``zero'' when precision matters (data, engineering, technical communication) or when avoiding confusion.
Yes, the Australian country code +61 replaces the leading 0 when dialing an Australian phone number from overseas; you drop the 0 from the area code or mobile number and add 61 after your international access code (or just use +61 if your phone handles the international prefix). For example, an Australian mobile number 0412 345 678 becomes +61 412 345 678 for international calls.
English speakers have a tendency to make longer words shorter. One way of doing this is called clipping. In the case of zero the initial sound made by the letters 'zer' is clipped or removed leaving only the last sound made by the letter o. This is done to save time or to keep rhythm.
The slashed zero glyph is often used to distinguish the digit "zero" ("0") from the Latin script letter "O" anywhere that the distinction needs emphasis, particularly in encoding systems, scientific and engineering applications, computer programming (such as software development), and telecommunications.
The letter "o" ("oh") is also used in spoken English as the name of the number 0 when saying times in the 24-hour clock, particularly in English used by both British and American military forces.
You can see the difference by looking at the figures you typed in. The letter, O, is a circle. The number, 0, is an oval. You can also denote zero by putting 0 with a slash through it.
Mom and Mommy are old-English words, words that are stilled used in Birmingham and most parts of the West Midlands. It is said that when people from the West Midlands went to America many years ago they took the spelling with them, hence Americans use Mom and Mommy.
International format for telephone numbers
Use international format for content that will be used outside Australia. The international format uses a plus symbol '+' to represent the international prefix, followed by a country code ('61' for Australia).
No, +61 and 0011 are not the same; +61 is Australia's country code, while 0011 is Australia's international access code, meaning you dial 0011 before 61 (and the rest of the number) when calling from Australia, whereas you dial +61 (replacing the leading 0) when calling Australia from another country. The + symbol on mobile phones automatically acts as the international prefix (like Australia's 0011) for the country you're in.
If you're calling a UK phone number from outside the UK, you remove the first zero of the phone number. So if you're calling 01223 123456 from outside the UK, you'll dial +44 1223 123456. That's because +44 is the country code for the UK and has to be dialled when dialling any UK number internationally.
The slashed zero can be used in stoichiometry to avoid confusion with the symbol for oxygen (capital O). The slashed zero is also used in charting and documenting in the medical and healthcare fields to avoid confusion with the letter "O".
We also understand that "two point oh" is the way that Tim O'Reilly, credited with coining the term, says it.
0 pronounced like "oh" is a number. It even has it's own Wikipedia entry. 0 is a bit unique in that it has a lot of names - zero, oh, nought, nil etc - that are in use fairly regularly. 12/twelve/a dozen is the only one that really comes close.
Zero is commonly used in a general way to mean none or nothing. Synonyms for this sense of the word include nil, naught, nought, and aught.
Ø or ⌀ is sometimes also used as a symbol for average value, particularly in German-speaking countries. ("Average" in German is Durchschnitt, directly translated as cut-through.) Slashed zero is an alternate glyph for the zero character. Its slash does not extend outside the ellipse (except in handwriting).
Common names for the number 0 in English include zero, nought, naught (/nɔːt/), and nil. In contexts where at least one adjacent digit distinguishes it from the letter O, the number is sometimes pronounced as oh or o (/oʊ/).
Garner's says “aught” for “zero” is fully standard English. But be aware that Brits, in particular, might be saying something greater than zero, so you “ought” to avoid it unless the context is crystal clear.
Because O is short for zerO and as has been said, O and 0 look similar. When you are saying a number with a zero in it, it flows much better saying the one syllable “O” than the two syllable “zero”. That said, if I am trying to enunciate clearly, like giving an account number, I will still say “zero” as part of it.
Did you know that 0 (zero) is an oval, while O (the letter) is a circle? Many children confuse them, which can lead to mistakes in handwriting, numbers, and letter recognition.
and so does 0/0 = 2 and 0/0 = 6 and 0/0 = any real number. This is where it breaks down. Because there are so many (in fact, an infinite number) of ways that this division could be converted into a valid multiplication, we can conclude that this division isn't valid or indeterminate, to use the correct terminology).
