Find the sum and product of the hexadecimal values, a01 and 20cba.

We have that
a01
and
20cba

step 1
convert to decimal values
a01> [10*16²+0*16+1*16^0]---> [2560+1]> 2561

20cba--> [ 2*16^4+0*16^3+12*16^2+11*16^1+10*16^0]
=[131072+3072+176+10]
=134330

step 2
find the sum
2561+134330> 136891

step 3
find the product
2561*134330> 344019130

step 4
convert to hexadecimal> using a Hexadecimal calculator
the sum
136891> 216BB

the product
344019130> 148150BA
