multiplication is short hand for repeated addition. Addition is short for repeated increments, and the increment is the fundamental operation on integers, so:
1 x 2 is defined to be two ones added:
1 + 1 which is defined to a single increment operation starting at 1. So, you look at the number line
-1 0 1 2 3 4 and start at "1" and move to the right one space to get "2", so
1 x 2 = 2
since the ops commute,
2 x 1 = 2, which is starting a 2 and moving to the right zero times, landing you on 2.
1 x 1 is the same, but starting on 1. If you start on 1 and move 0 times,,,guess where you land?
1.
