Let's get this math done. We have 256 and we're going to multiply it by 17. This is the same as taking 256 and adding it to itself 17 times.
Step 1: 0 + 256 = 256
Step 2: 256 + 256 = 512
Step 3: 512 + 256 = 768
Step 4: 768 + 256 = 1024
Step 5: 1024 + 256 = 1280
Step 6: 1280 + 256 = 1536
Step 7: 1536 + 256 = 1792
Step 8: 1792 + 256 = 2048
Step 9: 2048 + 256 = 2304
Step 10: 2304 + 256 = 2560
Step 11: 2560 + 256 = 2816
Step 12: 2816 + 256 = 3072
Step 13: 3072 + 256 = 3328
Step 14: 3328 + 256 = 3584
Step 15: 3584 + 256 = 3840
Step 16: 3840 + 256 = 4096
Step 17: 4096 + 256 = 4352

So, 256*17 = 4352
