Calculation above is including -(-(-7)), both first negatives are timed and become a plus (+), and when you change the both first negative into a plus, you’ve made +(-7). Then, + times – equals negative. Then you got a negative seven. Are you confused? OK, here’s the formulation:

+ x + = +

– x – = +

+ x – = –

– x + = –

The negative sign (-) indicates multiplying the resulting number by the opposite of 1 (being, of course -1). So, to simplify that expression, we can replace each individual negative sign with the expression “(-1)*”

-1*(-1*(-1*7))

Then, we work from the innermost parenthesis out, remembering that -1*-1=+1.

-1*(-1*(-7))

-1*(7)

-7

– times a – = +

+ times a -= negative

answer= -7

-(7) a negative times a negative equals a negative.

-7 a negative times a positive equals a negative.

so negative and negative is a positive

now you are left with -(+7)

negative and a positive is negative

so the answer is -7

odd negatives equal negatives

–(–(–7)) 3 negatives, 3 is odd

-7

if you have an odd number of negative numbers, your answer will be negative.

in your problem you have 3 negatives, so your answer is negative
