Let's roll up our sleeves and solve this. We have 694 and we're going to multiply it by 23, essentially adding 694 to itself 23 times.
Step 1: 0 + 694 = 694
Step 2: 694 + 694 = 1388
Step 3: 1388 + 694 = 2082
Step 4: 2082 + 694 = 2776
Step 5: 2776 + 694 = 3470
Step 6: 3470 + 694 = 4164
Step 7: 4164 + 694 = 4858
Step 8: 4858 + 694 = 5552
Step 9: 5552 + 694 = 6246
Step 10: 6246 + 694 = 6940
Step 11: 6940 + 694 = 7634
Step 12: 7634 + 694 = 8328
Step 13: 8328 + 694 = 9022
Step 14: 9022 + 694 = 9716
Step 15: 9716 + 694 = 10410
Step 16: 10410 + 694 = 11104
Step 17: 11104 + 694 = 11798
Step 18: 11798 + 694 = 12492
Step 19: 12492 + 694 = 13186
Step 20: 13186 + 694 = 13880
Step 21: 13880 + 694 = 14574
Step 22: 14574 + 694 = 15268
Step 23: 15268 + 694 = 15962

So, 694*23 = 15962
