5510 = 1101112
Decimal 55 = 110111 Binary

Any integer can be written as sum of potencies to the power of 2, known as binary code.

Here’s the proof that 110111 is the correct result:

1×2^5 + 1×2^4 + 0x2^3 + 1×2^2 + 1×2^1 + 1×2^0 = 55

Now you already know the most important thing:

11011110 equals 552 if unsigned.

If 55 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 000110111 in which the leftmost bit is the sign bit, followed perhaps by more trailing 0’s, and then by magnitude bits.

The reason to have the binary signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 55 signed using two’s complement, will start with one or more 1’s, but the exact code for -55 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
