OK, let's work through this together. We're starting with 443 and we're going to multiply it by 11, which means we add 443 to itself 11 times.
Step 1: 0 + 443 = 443
Step 2: 443 + 443 = 886
Step 3: 886 + 443 = 1329
Step 4: 1329 + 443 = 1772
Step 5: 1772 + 443 = 2215
Step 6: 2215 + 443 = 2658
Step 7: 2658 + 443 = 3101
Step 8: 3101 + 443 = 3544
Step 9: 3544 + 443 = 3987
Step 10: 3987 + 443 = 4430
Step 11: 4430 + 443 = 4873

So, 443*11 = 4873
