This article explains how to use Mass Addition to add and sum all entered numbers.
On the Grasshopper, it is represented by either of the two above.
Adding and Summing All Input Values
By using Mass Addition, all input values can be added or summed.
Input data for multiple numbers to the Mass Addition(I) on the left.
In this case, we connected the data of four numerical values: 2, 6, 4, and 8.
The output is the sum of all the numerical values input from the Mass Addition(R).
In this case, 2 6 4 8 was performed and 20 was output as a result.
The Mass Addition(Pr) outputs the numbers added from the top in sequence.
In this case, the first number is 2, the second is 2+6 = 8, the third is 8+4 = 12, and the fourth is 12+8 = 20.
