Interesting note: as late as the 18th century, many mathematicians considered negative numbers to be "nonsense". Negative numbers did not become universally accepted as existing until about the same time that imaginary numbers did.
Before the wide-spread acceptance of negative numbers, payments were credits and deposits were debits.
A credit subtracted the payment from your balance, while a debit added the payment to your balance.
After the advent of negative numbers, it was shown that subtraction is simply adding a negative number. So a payment (which is a subtraction) can be reinterpreted to be a negative number being added to your balance.
An upward direction is usually considered positive.
In mathematics and physics, directions are often categorized as positive or negative based on a defined reference frame. For instance, on a number line, movements to the right are typically considered positive, while movements to the left are negative. In the Cartesian coordinate system, movement upwards (in the y-direction) is positive, whereas movement downwards is negative. Similarly, in a three-dimensional space, movement away from the origin can be considered positive, while movement towards it is negative.
It is considered neutral as it has no value.
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Mathematically speaking, 0 is neither positive nor negative. In machine language in computers, 0 is considered as "positive" since the negative flag is not set.
Work done by the system is considered as PositiveWork done on the system is considered as Negative
Lysine is considered a positive amino acid.
Electron flow is considered to be negative to positive whereas conventional current flow is considered to be positive to negative.
Sincerity is almost universally considered a positive trait.
Protons are considered positive.

Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative

The "anode" is usually considered to be "negative". However in some experiments such as Gel Electrophoresis the anode is positive.
Steps that are considered positive by one side are likely to be considered negative by the opposite side.
