# 8 bit binary number $01101110$ is on a computer using two’s complement representation. What should it be in decimal?

8 bit binary number $$01101110$$ is on a computer using two’s complement representation. What should it be in decimal?

My solution is:
reverse it to $$10010001$$
$$10010001+1 = 10010010$$
$$10010010$$ to decimal is $$146$$
answer is $$-146$$ but this seems incorrect.

Any ideas?

Th number is positive because the MSB is $$0$$. So simply $$01101110_2 = 64+32+8+4+2$$.
This is a positive number because the most significant bit (MSB) is $$0$$. So the decimal representation of $$01101110_2$$ is $$2^6+2^5+0+2^3+2^2+2^1+0=110$$
