Answer:
261
Step-by-step explanation:
Adding up two decimal numbers ( 45 + 216 ) expressed in binary using 8-bit unsigned precision
first we express the decimal numbers in 8-bit unsigned precision :
45 = 32 + 8 + 4 + 1 = 2^5 + 2^3 + 2^2 + 2^0 = 00101101
216 = 2^7 + 2^6 + 2^4 + 2^3 = 11011000
Adding the numbers together = 00101101
+ 11011000
= 100000101 = 261 ( an overflow occurred )
note : The maximum value that can be expressed with 8-bit unsigned precision is = 2^8 - 1 = 256
