Decimal 7 = 111 Binary
Any integer can be written as sum of potencies to the power of 2, known as binary code.
Here’s the proof that 111 is the correct result:
1×2^2 + 1×2^1 + 1×2^0 = 7

Now you already know the most important thing:
11110 equals 72 if unsigned.
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 7 signed using two’s complement, will start with one or more 1’s, but the exact code for -7 decimal depends on the signed number representation system and number of bits available.
Here you can convert binary to decimal.
