OK, let's crack this. We're given 169 and our task is to multiply it by 10. Essentially, we'll be adding 169 to itself 10 times.
Step 1: 0 + 169 = 169
Step 2: 169 + 169 = 338
Step 3: 338 + 169 = 507
Step 4: 507 + 169 = 676
Step 5: 676 + 169 = 845
Step 6: 845 + 169 = 1014
Step 7: 1014 + 169 = 1183
Step 8: 1183 + 169 = 1352
Step 9: 1352 + 169 = 1521
Step 10: 1521 + 169 = 1690

So, 169*10 = 1690
