Alright, let's solve this math problem step by step. First, we have the number 596. 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 596 and add it to itself 15 times.
Step 1: 0 + 596 = 596
Step 2: 596 + 596 = 1192
Step 3: 1192 + 596 = 1788
Step 4: 1788 + 596 = 2384
Step 5: 2384 + 596 = 2980
Step 6: 2980 + 596 = 3576
Step 7: 3576 + 596 = 4172
Step 8: 4172 + 596 = 4768
Step 9: 4768 + 596 = 5364
Step 10: 5364 + 596 = 5960
Step 11: 5960 + 596 = 6556
Step 12: 6556 + 596 = 7152
Step 13: 7152 + 596 = 7748
Step 14: 7748 + 596 = 8344
Step 15: 8344 + 596 = 8940

So, 596*15 = 8940
