Sure thing! We've got 607 and we're gonna multiply it by 23. That's the same as adding 607 to itself 23 times.
Step 1: 0 + 607 = 607
Step 2: 607 + 607 = 1214
Step 3: 1214 + 607 = 1821
Step 4: 1821 + 607 = 2428
Step 5: 2428 + 607 = 3035
Step 6: 3035 + 607 = 3642
Step 7: 3642 + 607 = 4249
Step 8: 4249 + 607 = 4856
Step 9: 4856 + 607 = 5463
Step 10: 5463 + 607 = 6070
Step 11: 6070 + 607 = 6677
Step 12: 6677 + 607 = 7284
Step 13: 7284 + 607 = 7891
Step 14: 7891 + 607 = 8498
Step 15: 8498 + 607 = 9105
Step 16: 9105 + 607 = 9712
Step 17: 9712 + 607 = 10319
Step 18: 10319 + 607 = 10926
Step 19: 10926 + 607 = 11533
Step 20: 11533 + 607 = 12140
Step 21: 12140 + 607 = 12747
Step 22: 12747 + 607 = 13354
Step 23: 13354 + 607 = 13961

So, 607*23 = 13961
