Let's roll up our sleeves and solve this. We have 63 and we're going to multiply it by 10, essentially adding 63 to itself 10 times.
Step 1: 0 + 63 = 63
Step 2: 63 + 63 = 126
Step 3: 126 + 63 = 189
Step 4: 189 + 63 = 252
Step 5: 252 + 63 = 315
Step 6: 315 + 63 = 378
Step 7: 378 + 63 = 441
Step 8: 441 + 63 = 504
Step 9: 504 + 63 = 567
Step 10: 567 + 63 = 630

So, 63*10 = 630
