Sure thing! We've got 52 and we're gonna multiply it by 40. That's the same as adding 52 to itself 40 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

So, 52*40 = 2080
