(6+)+(-1)+(-12) i will give brainllest

-7

Step-by-step explanation:

when you add a positive number to a negative number, the function is subtraction.

So the equation can be simplified to this: 6 - 1 - 12.

Since you are only subtracting, you can go 6-1 (5), and then 5-12, which gives you the answer of -7.

Hope this helps!
