Question

Verify a − (−b) = a + b for the values a=34 and b=56.​

Answer 1

⇝GIVEN :

Verify that :

a -(-b) = a + b

Values :

a = 34

b = 56

⇝SOLUTION :

❒First,

${\mapsto{\bf{a -(-b)}}}$

${\leadsto{\sf{34 - (- 56)}}}$

${\leadsto{\sf{34 + 56}}}$

${\red{\leadsto{\bf{\underline{90}}}}}$

❒Than,

${\mapsto{\bf{a + b}}}$

${\leadsto{\sf{34 + 56}}}$

${\red{\leadsto{\bf{\underline{90}}}}}$

❒So,

${\blue{\dashrightarrow{\bf{\green{90 = 90}}}}}$

${\blue{\dashrightarrow{\green{\bf{LHS = RHS}}}}}$

${\blue{\dashrightarrow{\purple{\bf{a -(-b) = a + b}}}}}$

Answer 2

Answer:

--=+

means if a-(-b)

to remove the bracket for single sign it would be a+b.

Step-by-step explanation:

Let a=34& b =56

34-(-56)

34+56

=90

Hence,90is the verified answer.
