Question

Раскройте скобки (-238+742)-42= -(-356+145)-56= (7*95-900)-7*95= -(795-9*99)-99*0= (-48+101-29)-101+29= -(-79-39+81)+81-39=

Answer 1

 

(-238+742)-42=504-42=462

-(-356+145)-56=211-56=155

(7*95-900)-7*95=-235-665=-900

(795-9*99)-99*0=-96-0=-96

(-48+101-29)-101+29=24-101+29=-48

-(-79-39+81)+81-39=37+81-39=79

 

 

 

 

Answer 2

(-238+742)-42=504-42=462

 -(-356+145)-56=356-145-56=155

(7*95-900)-7*95=(665-900)-665=-235-665=-900

  -(795-9*99)-99*0=-795+891-0=96

  (-48+101-29)-101+29 =24-101+29=-48

-(-79-39+81)+81-39=79+39-81+81-39=79
