Multiplication of Signed Numbers 7

Here's another one:

-4 x -2 x 10 x -1 x -6

If there's an even number of negatives, then the answer is positive!

(Pairs of negatives turn positive and there would be no negatives left!)

Four negatives...

-4 x -2 x 10 x -1 x -6 = 480

(I did this one in my head by doing 2 x 4 = 8... then 8 x 6 = 48...
then 48 x 10 = 480!)

Your turn:

-2 x 3 x 4 =

-1 x -5 x 6 =

2 x -5 x -1 x 8 =

-3 x 2 x -4 x -2 x 1 =

So, remember these!

The Rules:

+ x + = +

+ x - = -

- x + = -

- x - = +
