I do not understand this requirement in this lab. Extract byte n from word x?

For this example: getByte(0x12345678,1) = 0x56

I changed 0x12345678 into binary, we can get 0000 0000 0001 0010 0011 0100 0101 0110 0111 1000

and change 0x56 into binary. 0000 0000 0101 0110

If I Extract byte 1 from word 0x12345678, we can get the answer by from right to left: 0.

If I Extract byte 4 from word 0x12345678, we can get the answer by from right to left: 1000

If I Extract byte 8 from word 0x12345678, we can get the answer by from right to left: 0111 1000

Why this answer is 0x56, for binary is 0000 0000 0101 0110 for n =1?
