OK, let's work through this together. We're starting with 449 and we're going to multiply it by 11, which means we add 449 to itself 11 times.
Step 1: 0 + 449 = 449
Step 2: 449 + 449 = 898
Step 3: 898 + 449 = 1347
Step 4: 1347 + 449 = 1796
Step 5: 1796 + 449 = 2245
Step 6: 2245 + 449 = 2694
Step 7: 2694 + 449 = 3143
Step 8: 3143 + 449 = 3592
Step 9: 3592 + 449 = 4041
Step 10: 4041 + 449 = 4490
Step 11: 4490 + 449 = 4939

So, 449*11 = 4939
