Which of the following is a temporary storage used by

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

(125 × 64) ÷ (8 × 5) + (12.5)² – (144 ÷ 3) = ?

Simplify the following expression:

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

[(120)² ÷24 ×25] ÷ 250 =?

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

75% of (√64 × 8 - 16) × ? = 15²

[(4/3) + (5/6)] of 378 = ?

18(1/3) + 9(2/3) – 10(1/3) = 1(2/3) + ?

1404 ÷ 26 x 3 + 7 = ?²

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

46 – 5² + 8² + 3² = ? × 4

120 × 195 ÷ 13 - ? = 16²
