OK, let's crack this. We're given 447 and our task is to multiply it by 16. Essentially, we'll be adding 447 to itself 16 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
Step 8: 3129 + 447 = 3576
Step 9: 3576 + 447 = 4023
Step 10: 4023 + 447 = 4470
Step 11: 4470 + 447 = 4917
Step 12: 4917 + 447 = 5364
Step 13: 5364 + 447 = 5811
Step 14: 5811 + 447 = 6258
Step 15: 6258 + 447 = 6705
Step 16: 6705 + 447 = 7152

So, 447*16 = 7152
