how is matrices is applicable in our life?
Matrices were used to organize data.
Inverse matrices are defined only for square matrices.
it cant, its just a useful thing that you will be tested on and asked to know this stuff for the rest of your life probably for no reason because there is no reason to use this in the real world so there ya go, sorry!
No. Multiplication of matrices is, in general, non-commutative, due to the way multiplication is defined.
I'm not trying to be a smart-alec but school is real life. If you are learning about matrices in school that is part of your real life. Later in life I don't have a clue what profession you will have. You may or may not use matrices later that depends on your choices.
how is matrices is applicable in our life?
its not.
Unless your "everyday life" involves work in some area of engineering, you won't use matrices in your everyday life.
Matrices can be used to collect data. They can also be used in cryptography--the practice and study of hiding information.

Umm... first of all this question isn't grammatically correct, but I'll answer the question, "How useful are whole numbers in real life?". They are useful to know when you when you are taking an algebra class:)
Matrices are used to figure who is seeded in a contest like the NCAA basketball final four. Matrices are used in any calculation that has to do with multiple variables. In business the maximum that you charge for a ticket and make the most money, I have used matrices.
Matrices are tools to solve linear equations. Engineers use matrices in solving electrical problems in circuits using Thevenin's and Norton's theories.
its useful if you work as a architect
When taking a math examination is the most important real life example.
They could help you solve a Rubik's Cube.
