Alright, let's solve this math problem step by step. First, we have the number 654. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 27. So, we're going to take the number 654 and add it to itself 27 times.
Step 1: 0 + 654 = 654
Step 2: 654 + 654 = 1308
Step 3: 1308 + 654 = 1962
Step 4: 1962 + 654 = 2616
Step 5: 2616 + 654 = 3270
Step 6: 3270 + 654 = 3924
Step 7: 3924 + 654 = 4578
Step 8: 4578 + 654 = 5232
Step 9: 5232 + 654 = 5886
Step 10: 5886 + 654 = 6540
Step 11: 6540 + 654 = 7194
Step 12: 7194 + 654 = 7848
Step 13: 7848 + 654 = 8502
Step 14: 8502 + 654 = 9156
Step 15: 9156 + 654 = 9810
Step 16: 9810 + 654 = 10464
Step 17: 10464 + 654 = 11118
Step 18: 11118 + 654 = 11772
Step 19: 11772 + 654 = 12426
Step 20: 12426 + 654 = 13080
Step 21: 13080 + 654 = 13734
Step 22: 13734 + 654 = 14388
Step 23: 14388 + 654 = 15042
Step 24: 15042 + 654 = 15696
Step 25: 15696 + 654 = 16350
Step 26: 16350 + 654 = 17004
Step 27: 17004 + 654 = 17658

So, 654*27 = 17658
