a) \(276+158-176=\left(276-176\right)+158=100+158=258\)
b) \(175+217+325+283\)
\(=\left(175+325\right)+\left(217+283\right)\)
\(=500+500\)
\(=1000\)
a. 276 +158 - 176 = ( 276 - 176 ) + 158
= 100 + 158
= 258
b. 175 + 217 + 325 + 283 = ( 175 + 325 ) + ( 217 + 283 )
= 500 + 500
= 1000
a,276+158-176=(276-176)+158=100+158=258
b,175+217+325+283=(175+325)+(217+283)=500+500=1000
