OK, let's work through this together. We're starting with 356 and we're going to multiply it by 11, which means we add 356 to itself 11 times.
Step 1: 0 + 356 = 356
Step 2: 356 + 356 = 712
Step 3: 712 + 356 = 1068
Step 4: 1068 + 356 = 1424
Step 5: 1424 + 356 = 1780
Step 6: 1780 + 356 = 2136
Step 7: 2136 + 356 = 2492
Step 8: 2492 + 356 = 2848
Step 9: 2848 + 356 = 3204
Step 10: 3204 + 356 = 3560
Step 11: 3560 + 356 = 3916

So, 356*11 = 3916
