Alright, let's solve this math problem step by step. First, we have the number 83. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 45. So, we're going to take the number 83 and add it to itself 45 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
Step 40: 3237 + 83 = 3320
Step 41: 3320 + 83 = 3403
Step 42: 3403 + 83 = 3486
Step 43: 3486 + 83 = 3569
Step 44: 3569 + 83 = 3652
Step 45: 3652 + 83 = 3735

So, 83*45 = 3735
