Let's roll up our sleeves and solve this. We have 289 and we're going to multiply it by 43, essentially adding 289 to itself 43 times.
Step 1: 0 + 289 = 289
Step 2: 289 + 289 = 578
Step 3: 578 + 289 = 867
Step 4: 867 + 289 = 1156
Step 5: 1156 + 289 = 1445
Step 6: 1445 + 289 = 1734
Step 7: 1734 + 289 = 2023
Step 8: 2023 + 289 = 2312
Step 9: 2312 + 289 = 2601
Step 10: 2601 + 289 = 2890
Step 11: 2890 + 289 = 3179
Step 12: 3179 + 289 = 3468
Step 13: 3468 + 289 = 3757
Step 14: 3757 + 289 = 4046
Step 15: 4046 + 289 = 4335
Step 16: 4335 + 289 = 4624
Step 17: 4624 + 289 = 4913
Step 18: 4913 + 289 = 5202
Step 19: 5202 + 289 = 5491
Step 20: 5491 + 289 = 5780
Step 21: 5780 + 289 = 6069
Step 22: 6069 + 289 = 6358
Step 23: 6358 + 289 = 6647
Step 24: 6647 + 289 = 6936
Step 25: 6936 + 289 = 7225
Step 26: 7225 + 289 = 7514
Step 27: 7514 + 289 = 7803
Step 28: 7803 + 289 = 8092
Step 29: 8092 + 289 = 8381
Step 30: 8381 + 289 = 8670
Step 31: 8670 + 289 = 8959
Step 32: 8959 + 289 = 9248
Step 33: 9248 + 289 = 9537
Step 34: 9537 + 289 = 9826
Step 35: 9826 + 289 = 10115
Step 36: 10115 + 289 = 10404
Step 37: 10404 + 289 = 10693
Step 38: 10693 + 289 = 10982
Step 39: 10982 + 289 = 11271
Step 40: 11271 + 289 = 11560
Step 41: 11560 + 289 = 11849
Step 42: 11849 + 289 = 12138
Step 43: 12138 + 289 = 12427

So, 289*43 = 12427
