Sure thing, let's get straight to it. We start with 489 and we're going to multiply it by 35, which means adding 489 to itself 35 times.
Step 1: 0 + 489 = 489
Step 2: 489 + 489 = 978
Step 3: 978 + 489 = 1467
Step 4: 1467 + 489 = 1956
Step 5: 1956 + 489 = 2445
Step 6: 2445 + 489 = 2934
Step 7: 2934 + 489 = 3423
Step 8: 3423 + 489 = 3912
Step 9: 3912 + 489 = 4401
Step 10: 4401 + 489 = 4890
Step 11: 4890 + 489 = 5379
Step 12: 5379 + 489 = 5868
Step 13: 5868 + 489 = 6357
Step 14: 6357 + 489 = 6846
Step 15: 6846 + 489 = 7335
Step 16: 7335 + 489 = 7824
Step 17: 7824 + 489 = 8313
Step 18: 8313 + 489 = 8802
Step 19: 8802 + 489 = 9291
Step 20: 9291 + 489 = 9780
Step 21: 9780 + 489 = 10269
Step 22: 10269 + 489 = 10758
Step 23: 10758 + 489 = 11247
Step 24: 11247 + 489 = 11736
Step 25: 11736 + 489 = 12225
Step 26: 12225 + 489 = 12714
Step 27: 12714 + 489 = 13203
Step 28: 13203 + 489 = 13692
Step 29: 13692 + 489 = 14181
Step 30: 14181 + 489 = 14670
Step 31: 14670 + 489 = 15159
Step 32: 15159 + 489 = 15648
Step 33: 15648 + 489 = 16137
Step 34: 16137 + 489 = 16626
Step 35: 16626 + 489 = 17115

So, 489*35 = 17115
