What Are The Rules For Adding Positive Numbers And Negative Numbers?

Before we begin, here are some important tips:

• Negative sign and subtraction sign are really the same thing.
• Positive sign has no affect on negative numbers.
• When subtracting two numbers, use the sign of the larger number for the answer.

• Adding Positive Numbers:
  (a) 5 + 1 = +6 = 6
  
  
• Adding Negative Numbers:
  (a) -5 + (-1) =
      -5 - 1 = -6
  
  (b) -5 + (-1) =
      -(5 + 1) =
      -(6) = -6
  
  
• Adding Positive and Negative Numbers:
  (a) -6 + 14 =
      14 - 6 = 8
  
  (b) -6 + 14 =
      +(14 - 6) =
      +(8) = +8 = 8
  
  (c) 7 + (-11) =
      -(11 - 7) = -4
