Answer 2

Hexadecimal

1B will be the addition of hex digits F and C.

We know that in hex,

$10=A\\11=B\\12=C\\13=D\\14=E\\15=F$

Steps involved in addition of hex digits:

• Start with least significant hexadecimal digits.
• let sum $=$ summation of  two hex digits.
• If sum is greater than or equal to 16, then $Sum= Sum-16 \ and\ carry \ the \ rest.$

for addition of F and C,

$15+12=27$

Since $27\geq16$,

Therefore, $27-16=11$

11 means B with carry 1.

So, the addition of these hex digits will be 1B.
