Sure thing, let's get straight to it. We start with 46 and we're going to multiply it by 40, which means adding 46 to itself 40 times.
Step 1: 0 + 46 = 46
Step 2: 46 + 46 = 92
Step 3: 92 + 46 = 138
Step 4: 138 + 46 = 184
Step 5: 184 + 46 = 230
Step 6: 230 + 46 = 276
Step 7: 276 + 46 = 322
Step 8: 322 + 46 = 368
Step 9: 368 + 46 = 414
Step 10: 414 + 46 = 460
Step 11: 460 + 46 = 506
Step 12: 506 + 46 = 552
Step 13: 552 + 46 = 598
Step 14: 598 + 46 = 644
Step 15: 644 + 46 = 690
Step 16: 690 + 46 = 736
Step 17: 736 + 46 = 782
Step 18: 782 + 46 = 828
Step 19: 828 + 46 = 874
Step 20: 874 + 46 = 920
Step 21: 920 + 46 = 966
Step 22: 966 + 46 = 1012
Step 23: 1012 + 46 = 1058
Step 24: 1058 + 46 = 1104
Step 25: 1104 + 46 = 1150
Step 26: 1150 + 46 = 1196
Step 27: 1196 + 46 = 1242
Step 28: 1242 + 46 = 1288
Step 29: 1288 + 46 = 1334
Step 30: 1334 + 46 = 1380
Step 31: 1380 + 46 = 1426
Step 32: 1426 + 46 = 1472
Step 33: 1472 + 46 = 1518
Step 34: 1518 + 46 = 1564
Step 35: 1564 + 46 = 1610
Step 36: 1610 + 46 = 1656
Step 37: 1656 + 46 = 1702
Step 38: 1702 + 46 = 1748
Step 39: 1748 + 46 = 1794
Step 40: 1794 + 46 = 1840

So, 46*40 = 1840
