Sure thing, let's get straight to it. We start with 261 and we're going to multiply it by 30, which means adding 261 to itself 30 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
Step 8: 1827 + 261 = 2088
Step 9: 2088 + 261 = 2349
Step 10: 2349 + 261 = 2610
Step 11: 2610 + 261 = 2871
Step 12: 2871 + 261 = 3132
Step 13: 3132 + 261 = 3393
Step 14: 3393 + 261 = 3654
Step 15: 3654 + 261 = 3915
Step 16: 3915 + 261 = 4176
Step 17: 4176 + 261 = 4437
Step 18: 4437 + 261 = 4698
Step 19: 4698 + 261 = 4959
Step 20: 4959 + 261 = 5220
Step 21: 5220 + 261 = 5481
Step 22: 5481 + 261 = 5742
Step 23: 5742 + 261 = 6003
Step 24: 6003 + 261 = 6264
Step 25: 6264 + 261 = 6525
Step 26: 6525 + 261 = 6786
Step 27: 6786 + 261 = 7047
Step 28: 7047 + 261 = 7308
Step 29: 7308 + 261 = 7569
Step 30: 7569 + 261 = 7830

So, 261*30 = 7830
