Sure thing! We've got 394 and we're gonna multiply it by 18. That's the same as adding 394 to itself 18 times.
Step 1: 0 + 394 = 394
Step 2: 394 + 394 = 788
Step 3: 788 + 394 = 1182
Step 4: 1182 + 394 = 1576
Step 5: 1576 + 394 = 1970
Step 6: 1970 + 394 = 2364
Step 7: 2364 + 394 = 2758
Step 8: 2758 + 394 = 3152
Step 9: 3152 + 394 = 3546
Step 10: 3546 + 394 = 3940
Step 11: 3940 + 394 = 4334
Step 12: 4334 + 394 = 4728
Step 13: 4728 + 394 = 5122
Step 14: 5122 + 394 = 5516
Step 15: 5516 + 394 = 5910
Step 16: 5910 + 394 = 6304
Step 17: 6304 + 394 = 6698
Step 18: 6698 + 394 = 7092

So, 394*18 = 7092
