Sure thing! We've got 279 and we're gonna multiply it by 9. That's the same as adding 279 to itself 9 times.
Step 1: 0 + 279 = 279
Step 2: 279 + 279 = 558
Step 3: 558 + 279 = 837
Step 4: 837 + 279 = 1116
Step 5: 1116 + 279 = 1395
Step 6: 1395 + 279 = 1674
Step 7: 1674 + 279 = 1953
Step 8: 1953 + 279 = 2232
Step 9: 2232 + 279 = 2511

So, 279*9 = 2511
