When you have two different signs together (a plus and a minus) the minus takes precedence (the minus "wins"). So, for example, 9 + -3 = 9 - 3 = 6.
Same mathematical signs equal plus Different mathematical signs equal minus Plus Plus = Plus (+)(+) = + Minus Minus = Plus (-)(-) = + Plus Minus = Minus (+)(-) = - Minus Plus = Minus (-)(+) = - So the direct answer to your question would be: plus minus equals minus
Yes it does. A minus is the opposite of something, so the minus of a minus is a plus.
plus For example: (+15) + (+1) = +16 or 16 But minus plus minus is equals to minus itself For example: (- 8) - (- 4) = - 4
