    Seeking formula for cumulative sum

    I need a formula for cumulative sum. Consider:

    +--+---+
    | 1| 1|
    +--+---+
    | 1| 2|
    +--+---+
    | 2| 4|
    +--+---+
    | 3| 7|
    +--+---+
    | 4| 11|
    +--+---+
    | 5| 16|
    +--+---+
    | 6| 22|
    +--+---+
    | 7| 29|
    +--+---+
    | 8| 37|
    +--+---+
    | 9| 46|
    +--+---+
    |10| 56|
    +--+---+
    |11| 67|
    +--+---+
    |12| 79|
    +--+---+
    |13| 92|
    +--+---+
    |14|106|
    +--+---+

    The formula for B1 would be =(A1).
    For B2 => =(A1+B1).
    For B3 => =(A1+B1+C1).
    Etc.

    Programming each Cell in Column B could get tedious .
    Is there a better way?

    Thanks

    b1 = sum($a$1:$a1)

    and drag down

    Great. Thanks, but there is a problem. My fault.
    I forgot to mention that there are two rows of test column titles etc. at the top of the table.
    This formula gives a result like:

    +--+---+
    | 1| 0|
    +--+---+
    | 1| 0|
    +--+---+
    | 2| 1|
    +--+---+
    | 3| 2|
    +--+---+
    ...


    How do I fix that?
    Thanks again
