Without delay, let's solve this. We've got 158 and we will be multiplying it by 11, that is, adding 158 to itself 11 times.
Step 1: 0 + 158 = 158
Step 2: 158 + 158 = 316
Step 3: 316 + 158 = 474
Step 4: 474 + 158 = 632
Step 5: 632 + 158 = 790
Step 6: 790 + 158 = 948
Step 7: 948 + 158 = 1106
Step 8: 1106 + 158 = 1264
Step 9: 1264 + 158 = 1422
Step 10: 1422 + 158 = 1580
Step 11: 1580 + 158 = 1738

So, 158*11 = 1738
