Simplify the following expression.
( 5 × 5 + 5 − 5 × 5 + 5 − 5 × 5 ) + ( 5 × 5 ) ÷ 5 ( 2 + 3 )
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2, i.e., 10.
First, simplify inside each part.
(5 × 5 + 5 − 5 × 5 + 5 − 5 × 5) = (25 + 5 − 25 + 5 − 25) = −15
(5 × 5) ÷ 5 (2 + 3) = 25 ÷ 5 × 5 = 5 × 5 = 25
Add both parts: −15 + 25 = 10
