Alright, let's solve this math problem step by step. First, we have the number 616. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 18. So, we're going to take the number 616 and add it to itself 18 times.
Step 1: 0 + 616 = 616
Step 2: 616 + 616 = 1232
Step 3: 1232 + 616 = 1848
Step 4: 1848 + 616 = 2464
Step 5: 2464 + 616 = 3080
Step 6: 3080 + 616 = 3696
Step 7: 3696 + 616 = 4312
Step 8: 4312 + 616 = 4928
Step 9: 4928 + 616 = 5544
Step 10: 5544 + 616 = 6160
Step 11: 6160 + 616 = 6776
Step 12: 6776 + 616 = 7392
Step 13: 7392 + 616 = 8008
Step 14: 8008 + 616 = 8624
Step 15: 8624 + 616 = 9240
Step 16: 9240 + 616 = 9856
Step 17: 9856 + 616 = 10472
Step 18: 10472 + 616 = 11088

So, 616*18 = 11088
