Without delay, let's solve this. We've got 118 and we will be multiplying it by 40, that is, adding 118 to itself 40 times.
Step 1: 0 + 118 = 118
Step 2: 118 + 118 = 236
Step 3: 236 + 118 = 354
Step 4: 354 + 118 = 472
Step 5: 472 + 118 = 590
Step 6: 590 + 118 = 708
Step 7: 708 + 118 = 826
Step 8: 826 + 118 = 944
Step 9: 944 + 118 = 1062
Step 10: 1062 + 118 = 1180
Step 11: 1180 + 118 = 1298
Step 12: 1298 + 118 = 1416
Step 13: 1416 + 118 = 1534
Step 14: 1534 + 118 = 1652
Step 15: 1652 + 118 = 1770
Step 16: 1770 + 118 = 1888
Step 17: 1888 + 118 = 2006
Step 18: 2006 + 118 = 2124
Step 19: 2124 + 118 = 2242
Step 20: 2242 + 118 = 2360
Step 21: 2360 + 118 = 2478
Step 22: 2478 + 118 = 2596
Step 23: 2596 + 118 = 2714
Step 24: 2714 + 118 = 2832
Step 25: 2832 + 118 = 2950
Step 26: 2950 + 118 = 3068
Step 27: 3068 + 118 = 3186
Step 28: 3186 + 118 = 3304
Step 29: 3304 + 118 = 3422
Step 30: 3422 + 118 = 3540
Step 31: 3540 + 118 = 3658
Step 32: 3658 + 118 = 3776
Step 33: 3776 + 118 = 3894
Step 34: 3894 + 118 = 4012
Step 35: 4012 + 118 = 4130
Step 36: 4130 + 118 = 4248
Step 37: 4248 + 118 = 4366
Step 38: 4366 + 118 = 4484
Step 39: 4484 + 118 = 4602
Step 40: 4602 + 118 = 4720

So, 118*40 = 4720
