Which of the following is/are the property (ies) of multiplication in integers? I. Multiplication is associative II. Multiplication is closed III. Multiplication distributes over addition
After teaching the concept of multiplication to her class, a teacher asked her children to multiply 48 by 4. One of her students solved it orally as “To multiply 48 by 4, we first add 48 to 48, which makes 96 and then add another 96 to reach 192. So, the answer is 192”. What can you say about his / her strategy of multiplication?

A Class III student performs multiplication of 16 × 25 as follows:  16 × 25 = 8 × 2 × 5 × 5 16 × 25 = 8 × 5 × 2 × 5 16 × 25 = 40 × 10 16 × 25 = 400 Which property of multiplication has the student used in this question?
Assume that multiplying a matrix G1 of dimension ? × ? with another matrix G2 of dimension ? × ? requires ??? scalar multiplications. Computing the product of n matrices G1G2G3…Gn can be done by parenthesizing in different ways. Define Gi Gi+1 as an explicitly computed pair for a given paranthesization if they are directly multiplied. For example, in the matrix multiplication chain G1G2G3G4G5G6 using parenthesization (G1(G2G3))(G4(G5G6)), G2G3 and G5G6 are the only explicitly computed pairs.Consider a matrix multiplication chain F1F2F3F4F5, where matrices F1, F2, F3, F4 and F5 are of dimensions 2 × 25, 25 × 3, 3 × 16, 16 × 1 and 1 × 1000, respectively. In the parenthesization of F1F2F3F4F5 that minimizes the total number of scalar multiplications, the explicitly computed pairs is/are
