So.......for clarity...........u take....................2, 3, 4, 5, 6, 7, 8, 9, 10, 11.....................TEN numbers.........and add them.........to -1, - 2, - 3, etc..................................start with 2.........and work backwards....................which is counterintuitive.......................so pair...............2 with -1 which equals..............1..........................b/c -1 + 2 = 1.................................- 2 + 3 = 1........................doing that gives u 10 ones..................then start again at 2.............and pair it with - 11..............since there are ten numbers in what I call the prime fundamental...............................they would overlap with any ten number sequence.........in the positive or negative direction.......................- 11 + 2 = - 9....................- 12 + 3 = -9............doing that ............gives u ten - 9s........................starting over with 2...............at - 21...........................- 21 + 2 = -19...............................................
