Without delay, let's solve this. We've got 98 and we will be multiplying it by 18, that is, adding 98 to itself 18 times.
Step 1: 0 + 98 = 98
Step 2: 98 + 98 = 196
Step 3: 196 + 98 = 294
Step 4: 294 + 98 = 392
Step 5: 392 + 98 = 490
Step 6: 490 + 98 = 588
Step 7: 588 + 98 = 686
Step 8: 686 + 98 = 784
Step 9: 784 + 98 = 882
Step 10: 882 + 98 = 980
Step 11: 980 + 98 = 1078
Step 12: 1078 + 98 = 1176
Step 13: 1176 + 98 = 1274
Step 14: 1274 + 98 = 1372
Step 15: 1372 + 98 = 1470
Step 16: 1470 + 98 = 1568
Step 17: 1568 + 98 = 1666
Step 18: 1666 + 98 = 1764

So, 98*18 = 1764
