Without delay, let's solve this. We've got 157 and we will be multiplying it by 8, that is, adding 157 to itself 8 times.
Step 1: 0 + 157 = 157
Step 2: 157 + 157 = 314
Step 3: 314 + 157 = 471
Step 4: 471 + 157 = 628
Step 5: 628 + 157 = 785
Step 6: 785 + 157 = 942
Step 7: 942 + 157 = 1099
Step 8: 1099 + 157 = 1256

So, 157*8 = 1256
