Alright, let's solve this math problem step by step. First, we have the number 447. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 7. So, we're going to take the number 447 and add it to itself 7 times.
Step 1: 0 + 447 = 447
Step 2: 447 + 447 = 894
Step 3: 894 + 447 = 1341
Step 4: 1341 + 447 = 1788
Step 5: 1788 + 447 = 2235
Step 6: 2235 + 447 = 2682
Step 7: 2682 + 447 = 3129

So, 447*7 = 3129
