Oct 19, 2015 · Mathematica question here. I'm looking to extract elements from a list that meet a certain criterion: namely, that the sum of the first and second elements is greater than or equal to 70. Here's what I've tried: points = Table [ {racing, sport, 8*racing + 12*sport}, {racing, 0, 40}, {sport, 0, 60}] selected = Select [points, points [ [All, All, 1]] + points [ [All, All, 2]] >= 70 &]

The mathematical functions that are built into Mathematica are mostly set up to be “listable” so that they act separately on each element of a list.

lst = { {4, 5}, {7, 8}, {9, 5}, {3, 2}, {1, 2}, {13, 12}}; #1 + RandomReal [ {1, 10}] & @@@ lst. This addresses your question of selecting elements one-by-one and adding a random number between 1 and 10 to it. If, as the title suggests, all you want to do is to pick the first element one-by-one, then you only need #1 & @@@ lst.
