Without delay, let's solve this. We've got 115 and we will be multiplying it by 7, that is, adding 115 to itself 7 times.
Step 1: 0 + 115 = 115
Step 2: 115 + 115 = 230
Step 3: 230 + 115 = 345
Step 4: 345 + 115 = 460
Step 5: 460 + 115 = 575
Step 6: 575 + 115 = 690
Step 7: 690 + 115 = 805

So, 115*7 = 805
