How to add a column step by step

Suppose I have column A with four numbers 1 3 4 2 and B with the result of each step

Thus B would display 1 4 8 10

I want to use a formula that adds up A, using only column A as input to column B

Thus column B would automatically be calculated as:

1 = 1

4 = 1+3

8 = 1+3+4

10 = 1+3+4+2

One way to do this is to use an "expanding range", like this:



=SUM(A$1:A1)


The $ is an anchor. When you drag down the range within the SUM function expands.

For functions, go in your menu to Help > Formulas and Functions Help


For general use of Numbers, see User Guide at Help > Numbers Help.


Note that most Numbers functions work the same as the equivalent Excel functions so you can also do an internet search. For example, for expanding ranges (more accurately expanding references) you can do a search for that and turn up results like this:
