Alright, let's solve this math problem step by step. First, we have the number 724. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 16. So, we're going to take the number 724 and add it to itself 16 times.
Step 1: 0 + 724 = 724
Step 2: 724 + 724 = 1448
Step 3: 1448 + 724 = 2172
Step 4: 2172 + 724 = 2896
Step 5: 2896 + 724 = 3620
Step 6: 3620 + 724 = 4344
Step 7: 4344 + 724 = 5068
Step 8: 5068 + 724 = 5792
Step 9: 5792 + 724 = 6516
Step 10: 6516 + 724 = 7240
Step 11: 7240 + 724 = 7964
Step 12: 7964 + 724 = 8688
Step 13: 8688 + 724 = 9412
Step 14: 9412 + 724 = 10136
Step 15: 10136 + 724 = 10860
Step 16: 10860 + 724 = 11584

So, 724*16 = 11584
