# Basic Matrix Row Operations Tips

There are four basic operations in mathematics: adding, subtracting, dividing and multiplying. It looks easy for a mathematician or a student who has maths as his or her major. In fact, these operations are quite simple: 2+2=4, 5-4=1 and so on. However, mathematics would have never become so much popular if it was so easy. An math homework may take ages for an ordinary high school, college or university student to find correct solutions. That is why many students require homework help in mathematics. There is nothing wrong in having problems or questions in maths. After all, we are not all geniuses. At the same time, it is still possible to get correct answers taking advantage of tips and special custom writing service companies which can be found online.

As already said above, there are 4 basic operations in maths. In case of matrices there are only three raw operations that this article will focus on.

Row switching. Every matrix consists of rows and columns of numbers. As the name of the operation suggests we switch rows of numbers and indicate substitutions with arrows. A word of advice – make sure you correctly copy the rows when switching them.

Row multiplication. In such a case you can either multiply rows of the two matrices or multiply a matrix by a certain number (in fact, anything you like). Thus, in case of two matrices you should multiply relevant numbers of the rows (for example, first right top numbers of matrix A and matrix B and so on). In case you multiply the whole matrix by one number, you perform multiplication operation with all matrix numbers.

Row addition. This operation is quite easy. One has to add relevant number of matrices (number 1 row 1 matrix A plus number 1 row 1 matrix B, and so on).

Students who need maths help can look for an online maths solver which a service that solves maths equations. In such a way you will not only get solutions to maths tasks but also learn solving “mechanics.”
