Sure thing, let's get straight to it. We start with 231 and we're going to multiply it by 14, which means adding 231 to itself 14 times.
Step 1: 0 + 231 = 231
Step 2: 231 + 231 = 462
Step 3: 462 + 231 = 693
Step 4: 693 + 231 = 924
Step 5: 924 + 231 = 1155
Step 6: 1155 + 231 = 1386
Step 7: 1386 + 231 = 1617
Step 8: 1617 + 231 = 1848
Step 9: 1848 + 231 = 2079
Step 10: 2079 + 231 = 2310
Step 11: 2310 + 231 = 2541
Step 12: 2541 + 231 = 2772
Step 13: 2772 + 231 = 3003
Step 14: 3003 + 231 = 3234

So, 231*14 = 3234
