hello everyone.Im stuck on the following question:a student designed a parallel binary adder for industry to add two 3 bit binary numbers together and display the sum and carry words in decimal on seven segment displays.The student wanted to economise the design and used a HAlf ADDER for the least and most significant bits.A FULL ADDER was used for the middle bits.If 5 and 7(decimal) are input,what will the sum word in decimal?
