Sure thing! We've got 69 and we're gonna multiply it by 18. That's the same as adding 69 to itself 18 times.
Step 1: 0 + 69 = 69
Step 2: 69 + 69 = 138
Step 3: 138 + 69 = 207
Step 4: 207 + 69 = 276
Step 5: 276 + 69 = 345
Step 6: 345 + 69 = 414
Step 7: 414 + 69 = 483
Step 8: 483 + 69 = 552
Step 9: 552 + 69 = 621
Step 10: 621 + 69 = 690
Step 11: 690 + 69 = 759
Step 12: 759 + 69 = 828
Step 13: 828 + 69 = 897
Step 14: 897 + 69 = 966
Step 15: 966 + 69 = 1035
Step 16: 1035 + 69 = 1104
Step 17: 1104 + 69 = 1173
Step 18: 1173 + 69 = 1242

So, 69*18 = 1242
