Sure thing, let's get straight to it. We start with 79 and we're going to multiply it by 11, which means adding 79 to itself 11 times.
Step 1: 0 + 79 = 79
Step 2: 79 + 79 = 158
Step 3: 158 + 79 = 237
Step 4: 237 + 79 = 316
Step 5: 316 + 79 = 395
Step 6: 395 + 79 = 474
Step 7: 474 + 79 = 553
Step 8: 553 + 79 = 632
Step 9: 632 + 79 = 711
Step 10: 711 + 79 = 790
Step 11: 790 + 79 = 869

So, 79*11 = 869
