Sure thing! We've got 261 and we're gonna multiply it by 7. That's the same as adding 261 to itself 7 times.
Step 1: 0 + 261 = 261
Step 2: 261 + 261 = 522
Step 3: 522 + 261 = 783
Step 4: 783 + 261 = 1044
Step 5: 1044 + 261 = 1305
Step 6: 1305 + 261 = 1566
Step 7: 1566 + 261 = 1827

So, 261*7 = 1827
