Alright, let's solve this math problem step by step. First, we have the number 52. 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 52 and add it to itself 45 times.
Step 1: 0 + 52 = 52
Step 2: 52 + 52 = 104
Step 3: 104 + 52 = 156
Step 4: 156 + 52 = 208
Step 5: 208 + 52 = 260
Step 6: 260 + 52 = 312
Step 7: 312 + 52 = 364
Step 8: 364 + 52 = 416
Step 9: 416 + 52 = 468
Step 10: 468 + 52 = 520
Step 11: 520 + 52 = 572
Step 12: 572 + 52 = 624
Step 13: 624 + 52 = 676
Step 14: 676 + 52 = 728
Step 15: 728 + 52 = 780
Step 16: 780 + 52 = 832
Step 17: 832 + 52 = 884
Step 18: 884 + 52 = 936
Step 19: 936 + 52 = 988
Step 20: 988 + 52 = 1040
Step 21: 1040 + 52 = 1092
Step 22: 1092 + 52 = 1144
Step 23: 1144 + 52 = 1196
Step 24: 1196 + 52 = 1248
Step 25: 1248 + 52 = 1300
Step 26: 1300 + 52 = 1352
Step 27: 1352 + 52 = 1404
Step 28: 1404 + 52 = 1456
Step 29: 1456 + 52 = 1508
Step 30: 1508 + 52 = 1560
Step 31: 1560 + 52 = 1612
Step 32: 1612 + 52 = 1664
Step 33: 1664 + 52 = 1716
Step 34: 1716 + 52 = 1768
Step 35: 1768 + 52 = 1820
Step 36: 1820 + 52 = 1872
Step 37: 1872 + 52 = 1924
Step 38: 1924 + 52 = 1976
Step 39: 1976 + 52 = 2028
Step 40: 2028 + 52 = 2080
Step 41: 2080 + 52 = 2132
Step 42: 2132 + 52 = 2184
Step 43: 2184 + 52 = 2236
Step 44: 2236 + 52 = 2288
Step 45: 2288 + 52 = 2340

So, 52*45 = 2340
