Alright, let's solve this math problem step by step. First, we have the number 744. 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 744 and add it to itself 15 times.
Step 1: 0 + 744 = 744
Step 2: 744 + 744 = 1488
Step 3: 1488 + 744 = 2232
Step 4: 2232 + 744 = 2976
Step 5: 2976 + 744 = 3720
Step 6: 3720 + 744 = 4464
Step 7: 4464 + 744 = 5208
Step 8: 5208 + 744 = 5952
Step 9: 5952 + 744 = 6696
Step 10: 6696 + 744 = 7440
Step 11: 7440 + 744 = 8184
Step 12: 8184 + 744 = 8928
Step 13: 8928 + 744 = 9672
Step 14: 9672 + 744 = 10416
Step 15: 10416 + 744 = 11160

So, 744*15 = 11160
