Let's roll up our sleeves and solve this. We have 512 and we're going to multiply it by 22, essentially adding 512 to itself 22 times.
Step 1: 0 + 512 = 512
Step 2: 512 + 512 = 1024
Step 3: 1024 + 512 = 1536
Step 4: 1536 + 512 = 2048
Step 5: 2048 + 512 = 2560
Step 6: 2560 + 512 = 3072
Step 7: 3072 + 512 = 3584
Step 8: 3584 + 512 = 4096
Step 9: 4096 + 512 = 4608
Step 10: 4608 + 512 = 5120
Step 11: 5120 + 512 = 5632
Step 12: 5632 + 512 = 6144
Step 13: 6144 + 512 = 6656
Step 14: 6656 + 512 = 7168
Step 15: 7168 + 512 = 7680
Step 16: 7680 + 512 = 8192
Step 17: 8192 + 512 = 8704
Step 18: 8704 + 512 = 9216
Step 19: 9216 + 512 = 9728
Step 20: 9728 + 512 = 10240
Step 21: 10240 + 512 = 10752
Step 22: 10752 + 512 = 11264

So, 512*22 = 11264
