Math Tips

  • When adding or substracting with negatives(-), keep these things in mind:

    (+) + (+) = (+)                    

    (-) + (-) = (-)

    (+) + (-) = ( take the sign of the LARGEST NUMBER and substract)

    EX:  8 + (-3) = 5

     (+) - (-) = [ double minus becomes a (+)]

    EX: 10 - (-5) = 5
