OK, let's crack this. We're given 69 and our task is to multiply it by 10. Essentially, we'll be adding 69 to itself 10 times.
Step 1: 0 + 69 = 69
Step 2: 69 + 69 = 138
Step 3: 138 + 69 = 207
Step 4: 207 + 69 = 276
Step 5: 276 + 69 = 345
Step 6: 345 + 69 = 414
Step 7: 414 + 69 = 483
Step 8: 483 + 69 = 552
Step 9: 552 + 69 = 621
Step 10: 621 + 69 = 690

So, 69*10 = 690
