    hi! I wasn’t sure about how the posatives and negatives worked, i was looking at my old notes but nothing really cleared it up for me…
    is it “+ plus += -” “- plus -= +” and “+ plus -= -” ??
    so confused!

    • Kyle Pearce Mr. Pearce says:


      With adding and subtracting, the sign which has the larger number wins…

      I.e.: -6 + 4 = -2 since there were more negatives than positive.

      When MULTIPLYING and DIVIDING, that’s when the sign rules work:

      + times + = +
      - times – = +

      + times – = -
      - times + = -

      Notice, multiplying same signs gives positive result.

      Multiplying opposite signs gives negative result.

      Good luck!

    hi! just a simple question that i just for some reason can’t find the answer too!
    if the question is “2n + 2m” would be the answer be the same as the question because there is no lke terms..or would you add 2 and 2 together?

What do you think? Give your say!
