Without delay, let's solve this. We've got 263 and we will be multiplying it by 7, that is, adding 263 to itself 7 times.
Step 1: 0 + 263 = 263
Step 2: 263 + 263 = 526
Step 3: 526 + 263 = 789
Step 4: 789 + 263 = 1052
Step 5: 1052 + 263 = 1315
Step 6: 1315 + 263 = 1578
Step 7: 1578 + 263 = 1841

So, 263*7 = 1841
