Sorry your question makes no sense. Yes it does make sense. the plus 44 part denotes that the number you are calling is in the UK. The 7 denotes that it is a mobile (cell) phone number. So this number isn't necessarily in London, it could be anywhere in the UK.
Outer London, UK
Plus
Its the country code
The expression is a single number which is equal to 7.
L represents the number 50. That would be 50 plus 10 plus 4 or 64.
A London (UK) phone number has 8 digits. If you wish to dial a London (UK) phone number from outside the London area (or a mobile phone) you need to prefix the 8 digits by the 3 digit London area code of 020 (which would normally be displayed in brackets before the number viz: (020) yxxx xxxx - the y is either 3, 7 or 8). If you wish to dial it from outside the UK, you'll need the international prefix for your country, followed by the country code of 44 plus the London area code without the leading zero plus the 8 digits, ie: +44 20 yxxx xxxx
If you mean GOOGOL, the next number is one googol plus 1.
The mean of a set of numbers is the average. That is to say, all the numbers added together and divided by the number of the numbers. the answer is 30.5
Total=sum or product of an eqation Multiply=to times or add that number by the times the other number Plus or Add=to add one number to another
That sum is 84. Since it's only one number, its mean is also 84. If those numbers were simply listed, without being added, then their mean would be 16.8 .
1 plus 1 does not mean anything it equals 2.?
No - that number format is a personal "follow-me" number. Large businesses such as banks do not use such numbers.
