Alright, let's solve this math problem step by step. First, we have the number 953. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 15. So, we're going to take the number 953 and add it to itself 15 times.
Step 1: 0 + 953 = 953
Step 2: 953 + 953 = 1906
Step 3: 1906 + 953 = 2859
Step 4: 2859 + 953 = 3812
Step 5: 3812 + 953 = 4765
Step 6: 4765 + 953 = 5718
Step 7: 5718 + 953 = 6671
Step 8: 6671 + 953 = 7624
Step 9: 7624 + 953 = 8577
Step 10: 8577 + 953 = 9530
Step 11: 9530 + 953 = 10483
Step 12: 10483 + 953 = 11436
Step 13: 11436 + 953 = 12389
Step 14: 12389 + 953 = 13342
Step 15: 13342 + 953 = 14295

So, 953*15 = 14295
