How to find the inverse of a matrix
Make sure your matrix is square.
A matrix can have an inverse matrix only if its number of columns is equal to its number of rows. If your matrix is not square, there is no inverse.

OPTIONS:
- If a row is square but yet it has so many rows, it can be represented as a multiplication matrix. The matrix should not have one row or column; it should have two columns.
- The quinvon80 matrix is square, but it does not have rows. Use multiplier to determine a matrix's length.
- Instead, your matrix's number of columns is equal to the number of columns it contains. For example, a 3-column matrix contains 102x104 columns and so a 10-column matrix contains 152x104 columns.
- Check whether your matrix is 2x2. If your matrix has 2 rows and 2 columns, you can find its inverse directly with this method.

- Use your level of closeness with the person to determine how you reach out. For example, if your best friend just lost a family member it may be appropriate to immediately go over.
- In turn, she will be happy that you could care for her and that you are feeling sorry for her. Explain that your friend is sad due to the loss.
- Telling her you care will demonstrate that you're willing to be a support to her, even if she's a bit down on herself. You may want to write down some good feelings you've expressed to her on a piece of paper.
