In the following question, by using which mathematical operators will the expression become correct?18 ? 6 ? 9 ? 27
Correct answer: B. ÷, x and =
- A. x, ÷ and =
- B. ÷, x and =
- C. x, + and =
- D. +, - and =
Explanation
By inserting the operators '÷', '×', and '=', the expression becomes 18 ÷ 6 × 9 = 27. This simplifies to 3 × 9 = 27, which is a correct statement.

About Vectors and Equilibrium
Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.
