(1) -340 and 170 from 45.
(ii) 865 and 493 from the difference of -380
and 675.​

Answer 1

Answer:

45-{-340+170}=45-(-170)=45+170=215

(-380-675)-(885+493)

-1055-1378=-2433

For subtraction number after from should be written first and negative number should be written in brackets, then there will be no mistake
