Simplify the following expression.
99 - [169 ÷ (13 × 13) - (-4) - {3 - 17 + 10}]
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 90.
99 - [169 ÷ (13 × 13) - (-4) - {3 - 17 + 10}]
= 99 - [169 ÷ 169 - (-4) - {3 - 17 + 10}]
= 99 - [1 - (-4) - {3 - 17 + 10}]
= 99 - [1 + 4 - {3 - 17 + 10}]
= 99 - [1 + 4 - {-4}]
= 99 - [1 + 4 + 4]
= 99 - [9]
= 99 - 9
= 90
Therefore, the value of the expression is 90.
