-8 + 16 = 8

Negative sixteen plus thirty two is 16. When a number is negative, subtract the negative number from the positive one to find the answer.

Negative 31 or Positive 1. The way you asked the question is confusing.

(16 plus 15) plus 15 = 46

-16. A negative+a negative=negative.

It is: -16+(-14) = -30

-16 + - 40 = -(16 + 40) = -56

Positive 16

-16+(-10) = -26

-16 .

Since both positive*positive and negative*negative equal a positive number, the square root of 16 can either be +4 or -4.

16

16 + 15 = 31

15 + 16 = 31

When you subtract a negative number, it has the same effect as adding a positive number. Therefore, in this instance, 16 - (-3) = 16 + 3 = 19.

Positive x Positive = Positive: 3 x 2 = 6Negative x Negative = Positive: (-2) x (-8) = 16Negative x Positive = Negative: (-3) x 4 = -12Positive x Negative = Negative: 3 x (-4) = -12

first, you square negative 4. Since negative times negative is positive, then you get positive sixteen., Then positive 16 times two is 32

-16 × -16 = +256

8

x^2 - 8x + 16 = 0(x )(x )You need two numbers that when multiplied are equal to 16, and when added are equal to 8.These two numbers are 4 and 4 (4 * 4 = 16, 4 + 4 = 16)Then you need to figure out if these are positive or negative. Since 16 is positive, you know that the numbers are either both positive or both negative. Since the 8 is negative, you know they must be negative.(x - 4)*(x - 4)

Positive sixteen (+16)

0.2

-18 + 16 = -2

there are no real answers to an even root (2,4,6,8) of any negative number. the innovation of i allows you to find the unreal answers. i= the fourth root of positive 16 is 2. so, the roots of -16 are positive and negative 2i. post script: you cannot have a real even root of a negative because a negative multiplied by a negative turns into a positive.
