OK, let's work through this together. We're starting with 164 and we're going to multiply it by 8, which means we add 164 to itself 8 times.
Step 1: 0 + 164 = 164
Step 2: 164 + 164 = 328
Step 3: 328 + 164 = 492
Step 4: 492 + 164 = 656
Step 5: 656 + 164 = 820
Step 6: 820 + 164 = 984
Step 7: 984 + 164 = 1148
Step 8: 1148 + 164 = 1312

So, 164*8 = 1312
