Question

Tính: 

a. 26 + (-6)

b. (-75) + 50

c. 80 + (-220)

Answer 1

a ) \(26+\left(-6\right)=20\)

b )  \(\left(-75\right)+50=-25\)

c )    \(80+\left(-200\right)=-120\)

 

Answer 2

 

a. 26 + (-6) = 20

b. (-75) + 50 = -25

 

c. 80 + (-220) = -140

Answer 3

a . 26 + ( - 6 ) = + ( 26 - 6 ) = 20

b . ( - 75 ) + 50 = + ( 75 - 50 ) = 25

c . 80 + ( - 220 ) = - ( 220 - 80 ) = - 140

Answer 4

\(26+\left(-6\right)=26-6=20\)

\(\left(-75\right)+50=-\left(75-50\right)=-25\)

\(80+\left(-20\right)=80-20=60\)

Answer 5

a) 26+(-6)=(26-6)=20

b)(-75)+50=(75-50)=25

c)80+9-220)=-(220-80)= -140

Answer 6

a ) 26 + (-6) = (26-6) = 20 

b) (-75)+50 = (75 - 50)=25

c )80+(-220)= - (220-80)= - 140

Answer 7

a. 26 + ( -6 ) =26 - 6 =20

b. ( -75 ) + 50 = -( 75 -50) = -25

c. 80 + ( -220 ) =80 -220 = -140
