The solution to the arithmetic problem Given are :

  • 9 + (-6) = 3
  • (-5) + 8 = 3
  • (-12) + (-6) = - 18
  • 10-(-8) = 18
  • (-4)-(+2)= - 6
  • -9-(-5) = - 4

Kindly take note of the following arithmetic rule :

  • - × - = +
  • + × - = -
  • - × + = -
  • + × + = +

Hence,

  • 9 + (-6) = 9 - 6 = 3

  • (-5) + 8 = - 5 + 8 = 3

  • (-12) + (-6) = - 12 - 6 = - 18

  • 10-(-8) = 10 + 8 = 18

  • (-4)-(+2)= - 4 - 2 = - 6

  • -9-(-5) = - 9 + 5 = - 4
