Sure thing! We've got 893 and we're gonna multiply it by 15. That's the same as adding 893 to itself 15 times.
Step 1: 0 + 893 = 893
Step 2: 893 + 893 = 1786
Step 3: 1786 + 893 = 2679
Step 4: 2679 + 893 = 3572
Step 5: 3572 + 893 = 4465
Step 6: 4465 + 893 = 5358
Step 7: 5358 + 893 = 6251
Step 8: 6251 + 893 = 7144
Step 9: 7144 + 893 = 8037
Step 10: 8037 + 893 = 8930
Step 11: 8930 + 893 = 9823
Step 12: 9823 + 893 = 10716
Step 13: 10716 + 893 = 11609
Step 14: 11609 + 893 = 12502
Step 15: 12502 + 893 = 13395

So, 893*15 = 13395
