Question

Evaluate -1^2. I am curious to see what the responses are.

Answer 1

-1

Answer 2

1

i am curious to know why you are curious

Answer 3

- 1 (if there is no parenthesis)

Answer 4

-1 squared is 1

i squared is -1

Answer 5

by looking at the above answer i wonder where the world is going.

-1^2 and (-1)^2 are not the same things but most of the answerers here gave tjhe answer to the second one.

-1^2 = -1 * 1^2 = -1

note that - (in fact -1 is there) is nor raised to the power 2.

similar example:

-2^2 = -4 because -2^2 = -1 * 2^2 = -4*4 = -4

cheers,

  

Answer 6

thats 1...

Answer 7

note

-1^2 = -1

but

(-1)^2 = +1

Answer 8

-(1)^2= -1

(-1)^2= 1

Answer 9

(-1)(-1)=1

Answer 10

(-1)² = -1*-1 = 1

-(1)² = -1² = -(1*1) = -1

Erm, if you're teaching Calculus and you're seeing this then, well, good luck.

And it's not surprising the answeres here are wrong, they are the vast majority of the time where there are 300 answers..lol.

What about that book of examples?

Answer 11

(-1)(-1) = 1

Answer 12

-1² = -1 * -1

-1² = 1

¯¯¯¯¯¯¯

Answer 13

as long as the expression is (-1)^2 when it's parenthesized, then the answer is just 1

Answer 14

1....

Answer 15

my answer is -1 because it has no quantity.

(-1)^2= 1

example:

-4^2=  -16

(-4)^2 = 16
