### is defined as the set of all sequences {\displaystyle (x_{i})_{i\in \mathbb {N} }} such that for each i, {\displaystyle x_{i}} is an element of {\displaystyle X_{i}} . The canonical projections are the maps pi : X → Xi defined by the equation {\displaystyle p_{i}((x_{j})_{j\in \mathbb {N} })=x_{i}} . Then the product topology on X is defined to be the coarsest topology (i.e. the topology with the fewest open sets) for which all the projections pi are continuous. The product topology is sometimes called the Tychonoff topology.

*I have a cell which has a basic formula in (adding up from 2 other cells) This number can end up being a minus number (-167), If this happens I need to be able to make that minus number appear as a zero (0). Is this possible? please help. =IF(A1+B1<0,0,A1+B1) Alternative =MAX(0,A1+B1) Gord Dibben Excel MVP On Sat, 7 May 2005 08:28:03 -0700, "marcus1066"* wrote: >I have a cell which has a basic formula in (adding up from 2 other cells) >This number can end up being a minus number (-167), If this happens I need to >be...

I want to a sequential number to fill in automatically each time the form is filled out. Malissa, A simple way would be to use something like this, you could assign it to a button, an open or before print event. Sheets("Sheet1").Range("A1").Value = _ Sheets("Sheet1").Range("A1").Value + 1 For other ways to do this or if this is going to be used in a temple have a look here http://www.mcgimpsey.com/excel/udfs/sequentialnums.html -- Paul B Always backup your data before trying something new Please post any response to the newsgroups so others...

__Although sequences are a type of function, they are usually distinguished notationally from functions in that the input is written as a subscript rather than in parentheses, i.e. an rather than f(n). There are terminological differences as well: the value of a sequence at the input 1 is called the "first element" of the sequence, the value at 2 is called the "second element", etc. Also, while a function abstracted from its input is usually denoted by a single letter, e.g. f, a sequence abstracted from its input is usually written by a notation such as {\displaystyle (a_{n})_{n\in A}} , or just as {\displaystyle (a_{n})} . Here A is the domain, or index set, of the sequence. sequential numbering in word__
