Without delay, let's solve this. We've got 490 and we will be multiplying it by 16, that is, adding 490 to itself 16 times.
Step 1: 0 + 490 = 490
Step 2: 490 + 490 = 980
Step 3: 980 + 490 = 1470
Step 4: 1470 + 490 = 1960
Step 5: 1960 + 490 = 2450
Step 6: 2450 + 490 = 2940
Step 7: 2940 + 490 = 3430
Step 8: 3430 + 490 = 3920
Step 9: 3920 + 490 = 4410
Step 10: 4410 + 490 = 4900
Step 11: 4900 + 490 = 5390
Step 12: 5390 + 490 = 5880
Step 13: 5880 + 490 = 6370
Step 14: 6370 + 490 = 6860
Step 15: 6860 + 490 = 7350
Step 16: 7350 + 490 = 7840

So, 490*16 = 7840
