What is the 2's complement value of -85?
87
What is the binary complement 8 bit representation for negative 19?
8-bit 2s complement representation of -19 is 11101101 For 1s complement invert all the bits. For 2s complement add 1 to the 1s complement: With 8-bits: 19 � 0001 0011 1s � 1110 1100 2s � 1110 1100 + 1 = 1110 1101
Why 2's complement binary subtraction is preffered over 1's complement binary subtraction?

What is binary equivalent of -15 using 2's complement?
-15 is 11111111 and 2s com is 1111 0001
What is the integer equivalent represented by 2's complement of the binary number 10001011?
To get the 2s complement, change all 1 bits to 0s and all 0 bits to 1s, and add 1 to the result. So the 2s complement of the 8-bit binary number 10001011 is the binary integer 01110101. If you want that in decimal, then remember that each place value column is twice the value of the place value column to its right, and the rightmost place value column for an integer is 1. Thus 01110101 in decimal is 64 + 32 + 16 + 4 + 1 = 117 (And 10001011 as a signed 8-bit binary integer represents the decimal integer -117.)
What is the value of s in the equation 4(2s 1) 7s 12?
If you mean: 4(2s-1) = 7s+12 then the value of s works out as 16
What is the difference between the place value of the 2s in 8234260?
What is the difference between the place value of the 2s in 8 234 260
How many 2's are there between 200-300?
100 2s for the hundreds digit of 200-30010 2s for the tens digit of 220-23010 2s for the ones digit of 200-300________________________________120 '2s'
What is the 2's complement value of 98?
To find the 2s complement invert the bits and add 1: 98 = 1100010 = ...0000 0110 0010 (written in complete nybbles with leading 0 bits) → 2's complement: ...1111 1001 1101 + 1 = ...1111 1001 1110 Every bit in front of the first bit is a 1 (the exact number will depend upon the number of bytes used to store the number).
How do you detect overflow when adding two numbers in 2s complement form?
You can detect overflow if the result turns out to be negative (which is the same as checking to see if the sign bit is 1). For example if you tried to add 5 and 6 in to 4-bit 2s complement, you would get 0101 + 0110 = 1011, which is a negative number since the sign bit (the 1 on the left) is a 1. This is an overflow.
What is the range of numbers that can be encoded in 4 bits using 2s complement notation?
Using 4 bits the signed range of numbers is -8 to 7. When working with signed numbers one bit is the sign bit, thus with 4 bits this leaves 3 bits for the value. With 3 bits there are 8 possible values, which when using 2s complement have ranges: for non-negative numbers these are 0 to 7; for negative numbers these are -1 to -8. Thus the range for signed 4 bit numbers is -8 to 7.
What is the 100-complement of 30?
