Sure thing, let's get straight to it. We start with 219 and we're going to multiply it by 15, which means adding 219 to itself 15 times.
Step 1: 0 + 219 = 219
Step 2: 219 + 219 = 438
Step 3: 438 + 219 = 657
Step 4: 657 + 219 = 876
Step 5: 876 + 219 = 1095
Step 6: 1095 + 219 = 1314
Step 7: 1314 + 219 = 1533
Step 8: 1533 + 219 = 1752
Step 9: 1752 + 219 = 1971
Step 10: 1971 + 219 = 2190
Step 11: 2190 + 219 = 2409
Step 12: 2409 + 219 = 2628
Step 13: 2628 + 219 = 2847
Step 14: 2847 + 219 = 3066
Step 15: 3066 + 219 = 3285

So, 219*15 = 3285
