convert 25 in to binary system and take two's complement of that.
u know how to convert 25 into binary. express it as
25 = 0 * 2^7+0 * 2^6+0 * 2^5+1 * 2^4+ 1 * 2^3+ 0 * 2^2 + 0 2^1+1 * 2^0
25 = 0001 1001
take one' complement : 1110 0110 toggle 1s and 0s
add 1 to this number : 1110 0111 this is -25

when some one gives a number 56, -23 with out a radix or base - it means the default base is 10. if some one gives a number like 56 base 16, then the base is 16. understand this.
is there is radix one want to specify, he can specify explicitly. if it is not specified we take a default, it is not wrong. it is right. The IDEA is HOW to represent a negative number in binary.
Ok u r telling that if we dosent write any base we need to consider it as decimal
what did your teacher tell u in ur class
he dosent told any thing such all the question in my text book it is shown the base never i hav seen such
hmm thnx u a teacher?Which state district school?
