Sure thing! We've got 209 and we're gonna multiply it by 10. That's the same as adding 209 to itself 10 times.
Step 1: 0 + 209 = 209
Step 2: 209 + 209 = 418
Step 3: 418 + 209 = 627
Step 4: 627 + 209 = 836
Step 5: 836 + 209 = 1045
Step 6: 1045 + 209 = 1254
Step 7: 1254 + 209 = 1463
Step 8: 1463 + 209 = 1672
Step 9: 1672 + 209 = 1881
Step 10: 1881 + 209 = 2090

So, 209*10 = 2090
