Question

-(-300)+(-210)-907+107

Answer 1

-(-300) + (-210) - 907 + 107 

= 300 - 210 - 907 + 107 

= ( 300 - 210 ) - ( 907 - 107 ) 

= 90 - 800

= -710

Answer 2

-(-300)+(-210)-907+107

= 300 + (-210) - 907 +107

= ( 300 - 210 ) - ( 907 - 107 ) 

= 90 - 800

= 90+(-80)

=-710

Answer 3

-(-300)+(-210)-907+107

= 300 - 210) - 907 +107

= ( 300 - 210 ) - ( 907 - 107 ) 

= 90 - 800

=-800 +  90

=-710

Answer 4

\(\text{-(-300)+(-210)-907+107}\)

\(=\text{300-210-907+107}\)

\(=\left(300-210\right)-\left(907-107\right)\)

\(=90-800=-710\)

Answer 5

-(-300) + (-210) - 907 + 107 

= 300 - 210 - 907 + 107 

= ( 300 - 210 ) - ( 907 - 107 ) 

= 90 - 800

= -710
