Question

Write the additive inverse of (-20).​

Answer 1

CORRECT QUESTION -

Write the additive inverse of (-20)!

CORRECT SOLUTION -

The additive inverse of -20 will be 20 .

• If a + b = 0 , then b is called negative or additive inverse of a & a is called additive inverse of b! So , in this case same thing will be applicable we will be keeping 20 + x = 0 = -20(x is the unknown additive inverse).

• We can know more by one fractional example : -2/3 additive inverse will be 2/3 and 2/3 additive inverse will be -2/3 ! [Notice no place is being changed i.e no reciprocal only signs are being changed!]

• Dont get confused with two terms multiplicative inverse & additive inverse both are different!

Answer 2

Answer:

The additive inverse of -20 is 20

Step-by-step explanation:

A number

N 's additive inverse N is a number that when added to N, will result to the additive identity, which is 0.

20+N =0

⇒N'=−20
