If a memory location is to contain a signed integer, then it will have a sign bit (zero means positive, one means negative). Also the negative numbers are represented by a complement (normally the two's complement). The article in the related link does a good explanation.
What this means: for example, an 8 bit location could represent 256 possible numbers. In an unsigned situation, this would be 0 to 255. But in a signed situation, the range is -128 to +127.

What does the negative sign do in excel?
The same as in many programming languages and other places where formulae are used. The negative sign can basically do one of the following: As a unary symbol (i.e., before a number), convert a positive to a negative, or a negative to a positive. For example, if "x" is positive, "-x" is negative, and vice versa. As a binary symbol (i.e., between two numbers), it means subtraction.
How is dividing integers similar to multiplying integers with the resulting sign?
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
What method of polar encoding is used for a binary value 10110 with seven transitions between negative and positive voltages?
Differential Manchester

6
How do you represent a negative number in Binary Coded Decimal?
All I know is that when a number is negative, you convert the decimal into binary and if it is negative you put 1111 before the binary digits.
Positive logic in a logic circuit is one in which?
In Positive logic, we all assume that the more positive (binary) voltage state is One, the less positive voltage state is Zero.Both voltage states could be positive, both could be negative, or they could be opposite polarities.
If a negative is divided by a positive is it negative?
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
