Without delay, let's solve this. We've got 264 and we will be multiplying it by 7, that is, adding 264 to itself 7 times.
Step 1: 0 + 264 = 264
Step 2: 264 + 264 = 528
Step 3: 528 + 264 = 792
Step 4: 792 + 264 = 1056
Step 5: 1056 + 264 = 1320
Step 6: 1320 + 264 = 1584
Step 7: 1584 + 264 = 1848

So, 264*7 = 1848
