Alright, let's solve this math problem step by step. First, we have the number 57. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 42. So, we're going to take the number 57 and add it to itself 42 times.
Step 1: 0 + 57 = 57
Step 2: 57 + 57 = 114
Step 3: 114 + 57 = 171
Step 4: 171 + 57 = 228
Step 5: 228 + 57 = 285
Step 6: 285 + 57 = 342
Step 7: 342 + 57 = 399
Step 8: 399 + 57 = 456
Step 9: 456 + 57 = 513
Step 10: 513 + 57 = 570
Step 11: 570 + 57 = 627
Step 12: 627 + 57 = 684
Step 13: 684 + 57 = 741
Step 14: 741 + 57 = 798
Step 15: 798 + 57 = 855
Step 16: 855 + 57 = 912
Step 17: 912 + 57 = 969
Step 18: 969 + 57 = 1026
Step 19: 1026 + 57 = 1083
Step 20: 1083 + 57 = 1140
Step 21: 1140 + 57 = 1197
Step 22: 1197 + 57 = 1254
Step 23: 1254 + 57 = 1311
Step 24: 1311 + 57 = 1368
Step 25: 1368 + 57 = 1425
Step 26: 1425 + 57 = 1482
Step 27: 1482 + 57 = 1539
Step 28: 1539 + 57 = 1596
Step 29: 1596 + 57 = 1653
Step 30: 1653 + 57 = 1710
Step 31: 1710 + 57 = 1767
Step 32: 1767 + 57 = 1824
Step 33: 1824 + 57 = 1881
Step 34: 1881 + 57 = 1938
Step 35: 1938 + 57 = 1995
Step 36: 1995 + 57 = 2052
Step 37: 2052 + 57 = 2109
Step 38: 2109 + 57 = 2166
Step 39: 2166 + 57 = 2223
Step 40: 2223 + 57 = 2280
Step 41: 2280 + 57 = 2337
Step 42: 2337 + 57 = 2394

So, 57*42 = 2394
