Add

Problem

[[3,1],[105,25],[70,1]]+[[250],[210],[210]]

Solution

1. Check dimensions for matrix addition. The first matrix has dimensions 3×2 (3 rows and 2 columns). The second matrix has dimensions 3×1 (3 rows and 1 column).

2. Identify the rule for matrix addition. Addition is only defined for matrices of the same dimensions.

3. Conclude that the operation is undefined because the number of columns in the first matrix does not match the number of columns in the second matrix.

Final Answer

The addition is undefined because the matrices have different dimensions.
