The likelihood is that the signs (+) and negative (-) derive from the associated math operations of addition (+) and subtraction (-) when performed on a null set (zero). The Welsh mathematician Robert Recorde (1510-1558), the designer of the equals (=) sign, introduced the modern use of plus and minus symbols to the UK in 1557. The Chinese worked with negative numbers as early as 200 AD, and mathematicians in India (either concurrently or later) used the (+) sign for negative numbers. Resistance to negative solutions was expressed by the Greeks, and later by Europeans as late as the year 1800. This seems hard to explain when we see that businesses routinely used "credits" and "debits" to their accounts during the entire period.

You add all the numbers with + signs and subtract all that have minus signs.

It is not completely clear. Other signs were used for the negative sign, such as the letter m for minus. In fact, in 1484 Chuquet used the m for minus. I will provide a great link with lots more info on the history of negative numbers.
