Which one of the following calcium salts is used as a

Solve the following equation.

143 + 14.3 + 1.43 + 0.143 + 0.0143 =?

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

? = (266 × 276) ÷ (114 × 161) × 17

8 × 9 + ? – 6 × 11 = 12 × 8

?³ - 25 × 11 = 30 - 15 × 12

18 × 15 + 86 – 58 =? + 38

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

(50 × 6 ÷ 12) × 9 = ?

√529 * 5 – 15% of 220 + ? = 120% of 160

√(8²  × 7  × 5² - 175) = ?

18 + 28 ÷ 4 - 14 = ? - 35
