Question

{(220-140)+[10×9+(-2×5)]}-100​

Answer 1

Answer:

Step-by-step explanation:

{(220-140)+[10×9+(-2×5)]}-100=60

={(220-140)+[10×9+(-10)]}-100

={(220-140)+[10×9-10]}-100

={(220-140)+[90-10]}-100

={(220-140)+80}-100

={80+80}-100

=160-100

=60

= {(220-140)+[10×9+(-2×5)]}-100=60

Answer 2

Answer:

=> 60

Step-by-step explanation:

Given that:-

$[(220-140)+[10\times 9+(-2\times 5)]]-100$

To find:- The value of the expression,

In order to solve that, we have to use the concept of BODMAS:

where,  

      B= bracket      

     O= order of power or rules      

     D= division      

     M= multiplication      

     A= addition      

     S= subtraction    

As we have,

=> $[(220-140)+[10\times 9+(-2\times 5)]]-100$

By further simplifying it, we get

=> $[(80)+[10\times 9+(-10)]]-100$

=> $[(80)+[10\times 9-10]]-100$

=> $[(80)+[90-10]]-100$

=> $[(80)+[80]]-100$

=> $160-100$

=> $60$

Hence, the required solution is 60.
