Whenever you see a subtraction sign then a negative sign, change them both to addition. Subtracting a negative is the same as adding a positive.

-128–52 is the same has -128+52

52/-5= -10.4 a negative*a negative=a positive

-15+-7(times)-2+-36+-15+84=

remember PEMDAS

-7*-2= 14

so, the question reads: -15+14+36+-15+84

Now, we can just get rid of the negative signs my rearranging the equation: We will just put the negative numbers on the back.

14+36+84-15-15

You can make this easier by combing like terms: that is, add the positive and add the negatives.

14+36+84= 134 -15-15=-30

so, 134-30=104

hope i helped!
