Math question - A Meeting of Minds

Kibby is taking algebra and her book say if you add two negatives you get a positive. How is that possible? We be confused.

Kath · Sep 24 2014, 06:30 PM

You don't.

If you multiply two negatives you get a positive.

What's the book called? Can you give us a direct quote from it?

Sounds like Kibby's dysgraphia is kicking in.

P'ter · Sep 25 2014, 04:22 AM

Multiplying and dividing: like signs give a possitive result.

Mixed signs give a negative.

Dysgraphia messing with being able to write, fine motor skill. Not reading.

I'll see if she can find what it says. It will be a couple of days it is an on line only book.

I use the word book loosely

Yes thats true - to negatives give you positive.
But its easy to remember in the way: two different signs zawsze give you negative and two same signs give you positive.

Only if you're multiplying or dividing.
