Answer 1

The answer would be -10

Explanation:

Reason would be that since -13 is surrounded by the symbol, you would make it positive 13, then add 17 to get 30. from there you can subtract 30 from 20 to get -10.

Answer 2

Answer: -10

Explanation:

• The absolute value function |x| basically gives the non-negative values for x, where w be any real number.

The given expression :
`20-||-13|+17|`

Since -13 is written in an absolute form , so |-13|=13

Then, the above expression becomes ,
`20-|13+17|=20-|30|`

Since 30 is already a positive number , so |30|=30

Then, the above expression becomes ,
`20-30=-10`

Hence, the final answer will be -10 .
