Answer:

Step-by-step explanation:

if you multiply a negative number with another negative number, it will be positive: ( - ) x ( - ) = ( + )

and if you multiply a negative number with a positive number, it will be negative: ( - ) x ( + ) = ( - )

so -(-4) = 4 and +(-9) = -9

-5+9-4+4-9-12+7=-10

I hope this helps
