Convert Hexadecimal to Decimal - CORRECT ANSWER-multiply each digit by 16 to power of n
digits
2A6_16 = 2 x 16^2 + 10 x 16^1 + 6 x 16^0
Convert Decimal to Binary - CORRECT ANSWER-Divide by 2, track the remainder, divide from
bottom up END AT 0
read remainders from top to bottom
Convert Decimal to Hexadecimal - CORRECT ANSWER-Divide by 16 and track the remainder,
divide from the bottom up END AT 0
read remainders from top to bottom,
REMEMBER A = 10, B = 11, etc.
Adding Binary Numbers - CORRECT ANSWER-Carry over in binary,
0110
+0110
1100
in this case,
column1 = 0 + 0,
, column2 = 1 + 1 = 2 (10, carry 1 keep 0), column3 = 1 + 1 + 1 =3 (11, carry 1 keep 1)
column4 = 1 + 0 + 0 = 1
If you carry out then there is.... - CORRECT ANSWER-Overflow
Determine which is positive 2 and negative 2
0010
1010 - CORRECT ANSWER-0010 - positive
1010 - negative
Finding 2s complements - CORRECT ANSWER-1. Invert number and add 1
2. Start from right, leave all bits up to, and including, first 1. Then invert the rest.
For adding 2s complements, C_in = ? - CORRECT ANSWER-C_out, if it doesn't then there is
OVERFLOW
How many full adders for 49 bits - CORRECT ANSWER-49 full adders (XOR set to B and SUB)
Order of Operations doesn't matter T or F - CORRECT ANSWER-(A + B) + C = A + (B + C)
Order of operands can be swapped T or F - CORRECT ANSWER-AB = BA
A+B=B+A
