OK, let's work through this together. We're starting with 477 and we're going to multiply it by 10, which means we add 477 to itself 10 times.
Step 1: 0 + 477 = 477
Step 2: 477 + 477 = 954
Step 3: 954 + 477 = 1431
Step 4: 1431 + 477 = 1908
Step 5: 1908 + 477 = 2385
Step 6: 2385 + 477 = 2862
Step 7: 2862 + 477 = 3339
Step 8: 3339 + 477 = 3816
Step 9: 3816 + 477 = 4293
Step 10: 4293 + 477 = 4770

So, 477*10 = 4770
