Sure thing, let's get straight to it. We start with 249 and we're going to multiply it by 14, which means adding 249 to itself 14 times.
Step 1: 0 + 249 = 249
Step 2: 249 + 249 = 498
Step 3: 498 + 249 = 747
Step 4: 747 + 249 = 996
Step 5: 996 + 249 = 1245
Step 6: 1245 + 249 = 1494
Step 7: 1494 + 249 = 1743
Step 8: 1743 + 249 = 1992
Step 9: 1992 + 249 = 2241
Step 10: 2241 + 249 = 2490
Step 11: 2490 + 249 = 2739
Step 12: 2739 + 249 = 2988
Step 13: 2988 + 249 = 3237
Step 14: 3237 + 249 = 3486

So, 249*14 = 3486
