Question

Evaluate -(77). My answer is 77. I'm not sure. Need help

Answer 1

imagine it written like this

0 - 77

what would you think the answer is then?

Answer 2

-77

Answer 3

correct,

-(77) and 0 - 77 are kind've the same thing.. except with 0 - 77, you have subtraction going on, and with -(77), you have multiplication.

another way to write -(77) would be (-1)*(77), or negative 1 times 77.

all you are doing is "pulling out" the negative sign from -77, and putting a -1 in front.

-77 = (-1)(77)

it's just another way to write it, math = re-writing things lol

Answer 4

Thanks a lot so -/81/ evaluating will be -81? Am I right?

Answer 5

not sure what you mean by the // sign, never seen that before
