OK, let's crack this. We're given 419 and our task is to multiply it by 8. Essentially, we'll be adding 419 to itself 8 times.
Step 1: 0 + 419 = 419
Step 2: 419 + 419 = 838
Step 3: 838 + 419 = 1257
Step 4: 1257 + 419 = 1676
Step 5: 1676 + 419 = 2095
Step 6: 2095 + 419 = 2514
Step 7: 2514 + 419 = 2933
Step 8: 2933 + 419 = 3352

So, 419*8 = 3352
