Answer 8

a) \(276+158-176=\left(276-176\right)+158=100+158=258\)

b) \(175+217+325+283\)

\(=\left(175+325\right)+\left(217+283\right)\)

\(=500+500\)

\(=1000\)

Answer 9

a. 276 +158 - 176 = ( 276 - 176 ) + 158

= 100 + 158

= 258

b. 175 + 217 + 325 + 283 = ( 175 + 325 ) + ( 217 + 283 )

= 500 + 500

= 1000

Answer 10

a,276+158-176=(276-176)+158=100+158=258

b,175+217+325+283=(175+325)+(217+283)=500+500=1000
