Answer 1

Răspuns:

800×[100-(26×2+2)]=

800×[100-(52+2)]=

800×(100-54)=

800×46= 36800

256×15-[(7000-723×4-8):100]=

3840-[(7000-2892-8):100]=

3840-[(4108-8):100]=

3840-(4100:100)=

3840-41= 3799

60×395-30×[1019-19×(5+3×3)]=

23700-30×[1019-19×(5+9)]=

23700-30×(1019-19×14)=

23700-30×(1019-266)=

23700-30×753=

23700-22590=1110
