800×[100-(26×2+2)]=
256×15-[(7000-723×4-8):100)]=
60×395-30×[1019-19×(5+3×3)]=​

Answer 1

1. 800×[100-(26×2+2)]=

= 800×[100-(52+2)

= 800×(100-54)

= 800×46

= 36.800

2. 256×15-[(7000-723×4-8):100)]=

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

= 3840-(4100:100)

= 3840-41

= 3799

3. 60×395-30×[1019-19×(5+3×3)]=

= 23.700-30×[1019-19×(5+9)]

= 23.700-30×(1019-19×14)]

= 23.700-30×(1019-266)

= 23.700-30×753

= 23.700-22.590

= 1110
