Show work and justify answer, this is not asking for a program but to write the steps by hand. Thank you.

Give an "and" instruction that replaces a number in DX with the remainder of the number when divided by $32.$

Instruction:

Justify your answer or show work.

If DX had $345$d$,$ after value in DX:

in hex$)$

Show work.

Suppose the register $CH$ contains an unsigned number whose value is between $0$ and $9.$

Note that ASCII for the characters, $\text{'}0\text{'},\text{'}1\text{'}$ and $\text{'}9\text{'}$ are $30h,31h,$ and $39h.$

Write a logical instruction to convert the value in $CH$ to the ASCII for the decimal digit corresponding to the value.

Instruction:

Justify your answer or show work.

If $CH$ had $6$d$,$ after value in CL: $.($in hex$)$ Show work.
