Sure thing, let's get straight to it. We start with 83 and we're going to multiply it by 39, which means adding 83 to itself 39 times.
Step 1: 0 + 83 = 83
Step 2: 83 + 83 = 166
Step 3: 166 + 83 = 249
Step 4: 249 + 83 = 332
Step 5: 332 + 83 = 415
Step 6: 415 + 83 = 498
Step 7: 498 + 83 = 581
Step 8: 581 + 83 = 664
Step 9: 664 + 83 = 747
Step 10: 747 + 83 = 830
Step 11: 830 + 83 = 913
Step 12: 913 + 83 = 996
Step 13: 996 + 83 = 1079
Step 14: 1079 + 83 = 1162
Step 15: 1162 + 83 = 1245
Step 16: 1245 + 83 = 1328
Step 17: 1328 + 83 = 1411
Step 18: 1411 + 83 = 1494
Step 19: 1494 + 83 = 1577
Step 20: 1577 + 83 = 1660
Step 21: 1660 + 83 = 1743
Step 22: 1743 + 83 = 1826
Step 23: 1826 + 83 = 1909
Step 24: 1909 + 83 = 1992
Step 25: 1992 + 83 = 2075
Step 26: 2075 + 83 = 2158
Step 27: 2158 + 83 = 2241
Step 28: 2241 + 83 = 2324
Step 29: 2324 + 83 = 2407
Step 30: 2407 + 83 = 2490
Step 31: 2490 + 83 = 2573
Step 32: 2573 + 83 = 2656
Step 33: 2656 + 83 = 2739
Step 34: 2739 + 83 = 2822
Step 35: 2822 + 83 = 2905
Step 36: 2905 + 83 = 2988
Step 37: 2988 + 83 = 3071
Step 38: 3071 + 83 = 3154
Step 39: 3154 + 83 = 3237

So, 83*39 = 3237
