Let's roll up our sleeves and solve this. We have 541 and we're going to multiply it by 8, essentially adding 541 to itself 8 times.
Step 1: 0 + 541 = 541
Step 2: 541 + 541 = 1082
Step 3: 1082 + 541 = 1623
Step 4: 1623 + 541 = 2164
Step 5: 2164 + 541 = 2705
Step 6: 2705 + 541 = 3246
Step 7: 3246 + 541 = 3787
Step 8: 3787 + 541 = 4328

So, 541*8 = 4328
