Complete the following arithmetic operations in two's complement representation. What are the values of the carry flag and overflow flag $($ignore them for multiply and divide instructions$).$

a$)-7+(-29)$

b$)31+11$

c$)15-19$

d$)-7(-3)$

e$)-7(3)$

f$)213$

All the values are in decimal, but binary equivalent is $6$ bits wide; so are the results.

CPU does not know that values are signed or unsigned although some of them have $-$ sign. So CPU$/$ALU will always update both carry flag and overflow flag.
