1.) just multiply the factors ,, then if the sign is

Example:

-4x-15= +60 or 60 4x15=

2.) If The factors Are

Example:

-4x15 = -60 4x-15 = -60

example:

+2 x+2

/2/x/2/

=4

-2 x+2

/2/x/2/

=4

in multiplying integers w/ various of numbers....multiply them all first then count the positive signs.....if the positive signs are even...the product's sign will be positive if it is

odd write negative

for instance: -2 x +3 x +4=

2x3x4 = +24

-2 x -3 x +4 =

2x3x4+ -24
