(2/5)(32% of 4500 – 440) = ? × 8

Simplify the following expression:

    (525 +175) ² - (525 – 175) ² / (525 × 175)

What will come in place of the question mark (?) in the following question?

24.30% of 372.32 = ?

Find the value of the given expression.

[76 – {90 ÷ 5 × (24 – 36 ÷ 3) ÷ 3}]

Solve the following equation.

143 + 14.3 + 1.43 + 0.143 + 0.0143 =?

1365 ÷ 15 + (? ÷ 5) = 6² × 3.5

√ (96 + 1000 + 3000) = ?

[∛(3375/19683  )- ∛(125/1728  )  ] ÷ ∛(64/729)  = ? - 3/8 

289 + 896 + 144 – 25% of 1100 =?

(32.1)² + (46.8)² - (28.8)² =? + 2257.97
