Sure thing! We've got 351 and we're gonna multiply it by 37. That's the same as adding 351 to itself 37 times.
Step 1: 0 + 351 = 351
Step 2: 351 + 351 = 702
Step 3: 702 + 351 = 1053
Step 4: 1053 + 351 = 1404
Step 5: 1404 + 351 = 1755
Step 6: 1755 + 351 = 2106
Step 7: 2106 + 351 = 2457
Step 8: 2457 + 351 = 2808
Step 9: 2808 + 351 = 3159
Step 10: 3159 + 351 = 3510
Step 11: 3510 + 351 = 3861
Step 12: 3861 + 351 = 4212
Step 13: 4212 + 351 = 4563
Step 14: 4563 + 351 = 4914
Step 15: 4914 + 351 = 5265
Step 16: 5265 + 351 = 5616
Step 17: 5616 + 351 = 5967
Step 18: 5967 + 351 = 6318
Step 19: 6318 + 351 = 6669
Step 20: 6669 + 351 = 7020
Step 21: 7020 + 351 = 7371
Step 22: 7371 + 351 = 7722
Step 23: 7722 + 351 = 8073
Step 24: 8073 + 351 = 8424
Step 25: 8424 + 351 = 8775
Step 26: 8775 + 351 = 9126
Step 27: 9126 + 351 = 9477
Step 28: 9477 + 351 = 9828
Step 29: 9828 + 351 = 10179
Step 30: 10179 + 351 = 10530
Step 31: 10530 + 351 = 10881
Step 32: 10881 + 351 = 11232
Step 33: 11232 + 351 = 11583
Step 34: 11583 + 351 = 11934
Step 35: 11934 + 351 = 12285
Step 36: 12285 + 351 = 12636
Step 37: 12636 + 351 = 12987

So, 351*37 = 12987
