Question

Which statement best explains the value of 16 − (−3)?

The additive inverse of −3 is −3, so 16 − (−3) = 19.
The additive inverse of −3 is −3, so 16 − (−3) = 13.
The additive inverse of −3 is +3, so 16 − (−3) = 19.
The additive inverse of −3 is +3, so 16 − (−3) = 13.

Answer 1

is one of those a 12 instead of a 13 in the answers

Answer 2

if not then it is c

Answer 3

What is the additive inverse of a number?

Answer 4

Also, subtraction is adding the additive inverse.
To subtract a - b, add the additive inverse of b to a, a - (-b).

Answer 5

Replace a with 16 and b with –3 in the definition of subtraction:
$$\huge a-b=a+(-b)$$
$$\huge 16-(-3)=16+(-(-3))$$
$$\huge 16-(-3)=16+(+3)$$
$$\huge 16-(-3)=16+3$$

Answer 6

To subtract b, add the opposite of b.

Answer 7

opposite of a number:

Each of the numbers in a pair such as 6 and –6

or –2.5 and 2.5.

Also called additive inverse.

The opposite of a number b is written as –b.

Caution: –b is not necessarily a negative number.

For example, if b = –3, then $$\huge –b = –(–3) = +3 = 3$$
