Perform the following arithmetic operation using 8-bit

two's complement

a) 8710 - 2910

i just want to know.. am i converting the number correctly?

89 = 0101 1001

-29 = 1110 0011

or...

i should change from decimal to binary...

then, apply two's complement to the number?

i know how to perform the arithmetic.. just bit confused with the representation of the number..
