slove the example 2 - (-7 )​

Answer 1

Given :- slove the example 2 - (-7 ) ?

Solution :-

→ 2 - (-7)

we know that , if we take negative sign out from bracket , and outside bracket also we have negative sign, both becomes positive .

so,

→ 2 - (-7)

→ 2 + 7

→ 9 (Ans.)

Remember :-

• (+) + (+) = + => 5 + 6 = 11
• (+) - (+) = + => 6 - 4 = 2
• (-) + (-) = - => (-2) + (-5) = (-7)
• (-) + (+) => Number which has greater sign => (-6) + 8 = 2 and, (-8) + 6 = (-2) since 8 > 6 .
• (+) - (-) = + => 4 - (-2) = 4 + 2 = 6 .

Answer 2

Given:

$2 - ( - 7)$

To find:

Solve the given sum.

Solution:

In integers, two signs are multiplied together.

$= > ( + ) \times ( + ) = +$

$= > ( + ) \times ( - ) = -$

$= > ( - ) \times ( + ) = -$

$= > ( - ) \times ( - ) = +$

The given question is :

$= > 2 - ( - 7)$

Multiply the given signs.

From the above, we know that minus x minus equals plus

$= > 2 + 7$

$= > 9$

Hence, the required answer => 2 - (-7) = 9
