State whether the following statements are true of false. If false, give a reason.
If A and B are two matrices of orders `3 xx 2 and 2 xx 3` respectively, then their sum A+B is possible.

The correct Answer is:
To determine whether the statement is true or false, we need to analyze the orders of the given matrices A and B. 1. **Identify the orders of the matrices:** - Matrix A has an order of \(3 \times 2\) (3 rows and 2 columns). - Matrix B has an order of \(2 \times 3\) (2 rows and 3 columns). 2. **Understand the condition for matrix addition:** - Two matrices can be added only if they have the same order (i.e., the same number of rows and columns). 3. **Compare the orders of matrices A and B:** - Matrix A has 3 rows and 2 columns. - Matrix B has 2 rows and 3 columns. - Since the number of rows and columns in both matrices are different, they do not have the same order. 4. **Conclusion:** - Since the orders of matrices A and B are not the same, their sum \(A + B\) is not possible. Therefore, the statement is **false**.
