Alright, let's solve this math problem step by step. First, we have the number 492. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 40. So, we're going to take the number 492 and add it to itself 40 times.
Step 1: 0 + 492 = 492
Step 2: 492 + 492 = 984
Step 3: 984 + 492 = 1476
Step 4: 1476 + 492 = 1968
Step 5: 1968 + 492 = 2460
Step 6: 2460 + 492 = 2952
Step 7: 2952 + 492 = 3444
Step 8: 3444 + 492 = 3936
Step 9: 3936 + 492 = 4428
Step 10: 4428 + 492 = 4920
Step 11: 4920 + 492 = 5412
Step 12: 5412 + 492 = 5904
Step 13: 5904 + 492 = 6396
Step 14: 6396 + 492 = 6888
Step 15: 6888 + 492 = 7380
Step 16: 7380 + 492 = 7872
Step 17: 7872 + 492 = 8364
Step 18: 8364 + 492 = 8856
Step 19: 8856 + 492 = 9348
Step 20: 9348 + 492 = 9840
Step 21: 9840 + 492 = 10332
Step 22: 10332 + 492 = 10824
Step 23: 10824 + 492 = 11316
Step 24: 11316 + 492 = 11808
Step 25: 11808 + 492 = 12300
Step 26: 12300 + 492 = 12792
Step 27: 12792 + 492 = 13284
Step 28: 13284 + 492 = 13776
Step 29: 13776 + 492 = 14268
Step 30: 14268 + 492 = 14760
Step 31: 14760 + 492 = 15252
Step 32: 15252 + 492 = 15744
Step 33: 15744 + 492 = 16236
Step 34: 16236 + 492 = 16728
Step 35: 16728 + 492 = 17220
Step 36: 17220 + 492 = 17712
Step 37: 17712 + 492 = 18204
Step 38: 18204 + 492 = 18696
Step 39: 18696 + 492 = 19188
Step 40: 19188 + 492 = 19680

So, 492*40 = 19680
