Can a matrix with dimensions of 3 X 6 be added to another matrix with dimensions of 6 X 3?
No, but it can be multiplied: The new matrix is 3x3. EG: 100100 100 200 010010 x 010 = 020 001001 001 002 100 010 001
Can a matrix with dimensions of 4 X 5 be added to another matrix with dimensions of 5 X 3?
No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.
What three numbers when multiplied equal 45?
3 x 3 x 5 = 451 x 3 x 15 = 45
Is it possible to multiply a 3 X 2 matrix and a 2 X 3 matrix?
The first matrix has 3 rows and 2 columns, the second matrix has 2 rows and 3 columns. Two matrices can only be multiplied together if the number of columns in the first matrix is equal to the number of rows in the second matrix. In the example shown there are 3 rows in the first matrix and 3 columns in the second matrix. And also 2 columns in the first and 2 rows in the second. Multiplication of the two matrices is therefore possible.
What x times 3?
