458.32 - 563.32 + 659.32 =?

135.37 – 50.24 + 629.09 – 199.50 = ? – 214.68 + 42.65

(25.111 % of 200) × 26 ÷ 12.99 – 18.88 × 15.82 + 150.33% of ³√ 4917 = ? – 200

25% of {(5/18) × 2880 + 12² } = ?% of 590

(18% of 360) ÷ 0.4 = ?

(286 ÷ 11 + 14) × 5 = 40 + 25% of ?

6612 ÷ 19 - ?% of 240 = -2196

√(2670+ √(1141+ √(260- √(1251- √(637+ √1521) ) ) ) )  =?

Determine the value of ‘x’ if x% of 500 plus {1250 ÷ x of 10} × 5 equals 130

Simplify: 3/5 + 0.4 × 2.5
