Sure thing, let's get straight to it. We start with 408 and we're going to multiply it by 11, which means adding 408 to itself 11 times.
Step 1: 0 + 408 = 408
Step 2: 408 + 408 = 816
Step 3: 816 + 408 = 1224
Step 4: 1224 + 408 = 1632
Step 5: 1632 + 408 = 2040
Step 6: 2040 + 408 = 2448
Step 7: 2448 + 408 = 2856
Step 8: 2856 + 408 = 3264
Step 9: 3264 + 408 = 3672
Step 10: 3672 + 408 = 4080
Step 11: 4080 + 408 = 4488

So, 408*11 = 4488
