Math Filters Front Sums Pick 4 The Front Sums filter is a so called "math filter". Math filters are created through calculations. You get the sum of a number by adding up the digits within that number. The pick 4 is the first digit of that sum. If the sum is only one digit the Front Sums filter returns 0. To show you how to calculate the Front Sums filter for a Pick 4 number here a step by step example.
Step 1: Divide the number into separate digits: 9017 => 9 0 1 7 Step 2: Add up the digits: 9 + 0 + 1 + 7 = 17 Step 3: Select only the first digit (or use 0 if there is none): 17 = 1
