Ravi uses the following step for solving an algebraic equation \(2x + 14 = 26\), \(2x = 26 - 14\). It is an example of :
Transposition
In the given equation, Ravi starts with \(2x + 14 = 26\) and rewrites it as \(2x = 26 - 14\).
The term 14, which was being added on the left-hand side, has been moved to the right-hand side, and its sign has changed from positive to negative.
This process of shifting a term from one side of an equation to the other side while reversing its sign is called transposition.
Hence, the given step is an example of transposition.

Which among the following statement is NOT true about the use of ICT in a mathematics classroom ?
For the Assertion (A) and Reason (R) given below, choose the correct option.
Assertion (A): Students should not be allowed to use calculators until they have shown mathematical proficiency with pencil and paper at foundational level.
Reason (R): The use of calculators for learning at foundational level prevents them from building a conceptual understanding of numerical relationships and operations.
