Sure thing, let's get straight to it. We start with 68 and we're going to multiply it by 18, which means adding 68 to itself 18 times.
Step 1: 0 + 68 = 68
Step 2: 68 + 68 = 136
Step 3: 136 + 68 = 204
Step 4: 204 + 68 = 272
Step 5: 272 + 68 = 340
Step 6: 340 + 68 = 408
Step 7: 408 + 68 = 476
Step 8: 476 + 68 = 544
Step 9: 544 + 68 = 612
Step 10: 612 + 68 = 680
Step 11: 680 + 68 = 748
Step 12: 748 + 68 = 816
Step 13: 816 + 68 = 884
Step 14: 884 + 68 = 952
Step 15: 952 + 68 = 1020
Step 16: 1020 + 68 = 1088
Step 17: 1088 + 68 = 1156
Step 18: 1156 + 68 = 1224

So, 68*18 = 1224
