Question

(-a) + b -b+ addnive inverse of _​

Answer 1

Answer:

additive inverse of (-a)+b-b is +a.

Step-by-step explanation:

Method-I:      (Important method & original method )

Given that,

(-a) + b - b       (∵ +b - b =0 )

⇒ (-a) + 0

⇒ (-a)

∴ The additive inverse of '-a' is '+a'.

Method-II:     (optional method )

Given that,

(-a) + b - b

now, find additive inverse separately for every term,

• The additive inverse of '-a' is '+a'
• The additive inverse of '+b' is '-b'
• The additive inverse of '-b' is '+b'

Now, add all the additive inverse

⇒ +a - b + b          (∵ -b + b = b - b = 0 )

⇒ a - 0

⇒ a

∴The additive inverse of (-a) + b - b = +a
