It can be a plus or a miuns - depending on which one of the two had a greater absolute value. Also, it will be nearer to zero than the larger of the two magnitudes.

∙ 12y agoyes you can. You can add and subtract ANY number, negative or positive, even if it is a decimal. For example 1 + 1 = 2 -1+-1 = -2 -1+1 = 0 A minus plus a minus is a minus. A minus plus a positive is a minus.
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.
Because adding a negative is the same as subtracting a positive. In other words, minus a plus is he same as plus a minus. For example 5+ (-3) = 5-3 = +2 5 -(+3) = 5-3 = +2 Remember minus a plus = = minus plus a minus = minus plus a plus = plus minus a minus = plus
2 - -2 = 2+2 when u minus a negative number you add it.
x = 10 Minus 6 times 10 = minus 60 Add 3 to minus 60 = minus 57

plus For example: (+15) + (+1) = +16 or 16 But minus plus minus is equals to minus itself For example: (- 8) - (- 4) = - 4

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
A plus + a plus is a plus.
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9
A minus plus a minus will give a sum with a minus also.
When you have a minus and a plus sign together, you simply ignore the plus sign. For example -5 + -3 is the same as -5 - 3 which is -8. If you have two minus signs together, you replace them with a plus sign. For example -5 - -3 is the same as -5 + 3 which gives -2. At school I learned a simple rule: 'Minus a minus is a plus'
