Alright, let's solve this math problem step by step. First, we have the number 36. 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 36 and add it to itself 42 times.
Step 1: 0 + 36 = 36
Step 2: 36 + 36 = 72
Step 3: 72 + 36 = 108
Step 4: 108 + 36 = 144
Step 5: 144 + 36 = 180
Step 6: 180 + 36 = 216
Step 7: 216 + 36 = 252
Step 8: 252 + 36 = 288
Step 9: 288 + 36 = 324
Step 10: 324 + 36 = 360
Step 11: 360 + 36 = 396
Step 12: 396 + 36 = 432
Step 13: 432 + 36 = 468
Step 14: 468 + 36 = 504
Step 15: 504 + 36 = 540
Step 16: 540 + 36 = 576
Step 17: 576 + 36 = 612
Step 18: 612 + 36 = 648
Step 19: 648 + 36 = 684
Step 20: 684 + 36 = 720
Step 21: 720 + 36 = 756
Step 22: 756 + 36 = 792
Step 23: 792 + 36 = 828
Step 24: 828 + 36 = 864
Step 25: 864 + 36 = 900
Step 26: 900 + 36 = 936
Step 27: 936 + 36 = 972
Step 28: 972 + 36 = 1008
Step 29: 1008 + 36 = 1044
Step 30: 1044 + 36 = 1080
Step 31: 1080 + 36 = 1116
Step 32: 1116 + 36 = 1152
Step 33: 1152 + 36 = 1188
Step 34: 1188 + 36 = 1224
Step 35: 1224 + 36 = 1260
Step 36: 1260 + 36 = 1296
Step 37: 1296 + 36 = 1332
Step 38: 1332 + 36 = 1368
Step 39: 1368 + 36 = 1404
Step 40: 1404 + 36 = 1440
Step 41: 1440 + 36 = 1476
Step 42: 1476 + 36 = 1512

So, 36*42 = 1512
