Question

76-4 - [6 +{19 - (48 - 57 - 17)}]​

Answer 1

# First Method -

76–4-[6+{19-(48–57–17)}]

= 76–4-[6+{19–48+57+17}]

= 76–4-[6+19–48+57+17]

= 76–4–6–19+48–57–17

= 76+48–4–6–19–57–17

= 124–103

= 21

# Second-method -

76–4-[6+{19-(48–57–17)}]

= 76–4-[6+{19-(-26)}]

= 76–4-[6+{19+26}]

= 76–4-[6+45)]

= 76–4–51

= 76–55

= 21

Answer = 21

Answer 2

Answer:

21

Step-by-step explanation:

76 - 4 - [ 6 + { 19 - ( 48 - 57 - 17) } ]

= ​76 - 4 - [ 6 + { 19 - ( 48 - 74 ) } ]

= 76 - 4 - [ 6 + { 19 - ( - 26 ) } ]

= 76 - 4 - [ 6 + { 19 + 26 } ]

= 76 - 4 - [ 6 + 45 ]

= 76 - 4 - 51

= 76 - 55

= 21
