OK, let's work through this together. We're starting with 58 and we're going to multiply it by 8, which means we add 58 to itself 8 times.
Step 1: 0 + 58 = 58
Step 2: 58 + 58 = 116
Step 3: 116 + 58 = 174
Step 4: 174 + 58 = 232
Step 5: 232 + 58 = 290
Step 6: 290 + 58 = 348
Step 7: 348 + 58 = 406
Step 8: 406 + 58 = 464

So, 58*8 = 464
