Add spreads

hi list
i would like to add slices in a spread like this:

0
0+1
0+1+2
0+1+2+3
0+1+2+3. … …+x

has anyone any idea how to do this . .or exists a node for this
. .thanx nos

if you only have numbers 0, 1, 2, 3, …, x you can calculate the result directly by:

x*(x+1)/2

but with arbitary spread slices, does the Integral (Spreads) node your job. it outputs every partial sum of a spread of values.

try the combination of an I (Spreads) and a + (Value Spectral) Node.

oh i see, thanx … differencial … .integral seems to be basic mathematical operations …
