Alright, let's solve this math problem step by step. First, we have the number 345. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 34. So, we're going to take the number 345 and add it to itself 34 times.
Step 1: 0 + 345 = 345
Step 2: 345 + 345 = 690
Step 3: 690 + 345 = 1035
Step 4: 1035 + 345 = 1380
Step 5: 1380 + 345 = 1725
Step 6: 1725 + 345 = 2070
Step 7: 2070 + 345 = 2415
Step 8: 2415 + 345 = 2760
Step 9: 2760 + 345 = 3105
Step 10: 3105 + 345 = 3450
Step 11: 3450 + 345 = 3795
Step 12: 3795 + 345 = 4140
Step 13: 4140 + 345 = 4485
Step 14: 4485 + 345 = 4830
Step 15: 4830 + 345 = 5175
Step 16: 5175 + 345 = 5520
Step 17: 5520 + 345 = 5865
Step 18: 5865 + 345 = 6210
Step 19: 6210 + 345 = 6555
Step 20: 6555 + 345 = 6900
Step 21: 6900 + 345 = 7245
Step 22: 7245 + 345 = 7590
Step 23: 7590 + 345 = 7935
Step 24: 7935 + 345 = 8280
Step 25: 8280 + 345 = 8625
Step 26: 8625 + 345 = 8970
Step 27: 8970 + 345 = 9315
Step 28: 9315 + 345 = 9660
Step 29: 9660 + 345 = 10005
Step 30: 10005 + 345 = 10350
Step 31: 10350 + 345 = 10695
Step 32: 10695 + 345 = 11040
Step 33: 11040 + 345 = 11385
Step 34: 11385 + 345 = 11730

So, 345*34 = 11730
