Can matrices of the same dimension be multiplied?
No. The number of columns of the first matrix needs to be the same as the number of rows of the second.So, matrices can only be multiplied is their dimensions are k*l and l*m. If the matrices are of the same dimension then the number of rows are the same so that k = l, and the number of columns are the same so that l = m. And therefore both matrices are l*l square matrices.
What is the condition for the addition of matrices?
The matrices must have the same dimensions.
Do all matrices have determinant?
Only square matrices have a determinant
What is the magnitude of the size change of the figures formed by these matrices?
There are no matrices in the question!
Do you multiply matrices?
I do not. I f*cking hate matrices. I multiply sheep.
Does the ring of full rank matrices form a domain?
The full rank matrices do not include zero, so they do not form a ring in the first place.
Can matrices of the same dimension be multiplied?
No. The number of columns of the first matrix needs to be the same as the number of rows of the second.So, matrices can only be multiplied is their dimensions are k*l and l*m. If the matrices are of the same dimension then the number of rows are the same so that k = l, and the number of columns are the same so that l = m. And therefore both matrices are l*l square matrices.
Can the elimnation matrices only be applied to square matrices?
Only square matrices have inverses.
What is a contributions credited to the Minoans?
The Minoans are credited as Europe's first great civilization.
Who is first credited with first understanding electricity?
Ben Franklin is first credited with understanding electricity.
How matrices applicable in daily life?

Do all matrices have determinant?
Only square matrices have a determinant
What is the condition for the addition of matrices?
The matrices must have the same dimensions.
What is the singular form of matrices?
The singular form of matrices is matrix.
Who is credited with the first successful airplane?
The Wright brothers are widely credited with the first successful airplane.
How do you add matrices?
You add matrices by adding their respective terms - e.g. the element in the first row and sixth column of the sum is the sum of the elements in the addends' first rows and sixth columns. Wikipedia has a nice example of matrix addition that I linked below.
Who discovered the matrix?
The first use of matrices to solve equation was back in 300 BC in a Chinese book called Nine Chapters of Mathematical Art by Chiu Chang Suan Shu. They did not use the name matrix. The use of that word came much later and is credited to James Sylvester in 1850.
