OK, let's work through this together. We're starting with 441 and we're going to multiply it by 7, which means we add 441 to itself 7 times.
Step 1: 0 + 441 = 441
Step 2: 441 + 441 = 882
Step 3: 882 + 441 = 1323
Step 4: 1323 + 441 = 1764
Step 5: 1764 + 441 = 2205
Step 6: 2205 + 441 = 2646
Step 7: 2646 + 441 = 3087

So, 441*7 = 3087
