Answer 2

Step-by-step explanation:

Hi,

=> [ (2) - 1 + (4) - 1 + (3) - 1 ) - 1 ]

First step : Remove all small brackets e

=> ( 2 - 1 + 4 - 1 + 3 - 1 ) - 1

Second step : keep positive and negative numbers together

=> ( 2 + 4 + 3 - 1 - 1 - 1 ) - 1

Third step : Add positive and negative numbers

=> ( 9 - 3 ) - 1

Fourth Step : Now subtract 3 from 9

=> (9-3) = 6

=> ( 6 ) - 1

=> 6 - 1

=> 5

Hence,

[ (2) - 1 + (4) - 1 + (3) - 1 ) - 1 ] = 5 [ Answer ]
