when you use the triangle method , you cross out what symbols are already there , your answer is the symbol that's left.

ex. -12 x 3. cross out one of your negitve sign and cross out your positive sign. you only have one sign left. your answer is -36

RULE - if there's an odd number of negatives = the answer is negative

if theres and even number of negatives = the answer is positive .

ex. -2 + -2 + 3 + -7 . there are 3 negative numbers , 3 is an old number so our answer is negative.
