## How to find value of expression: councils and recommendations |

You as parents, in the course of training of the child, will face need of the help in the solution of house tasks in mathematics, algebra and geometry more than once. And one of basic abilities which needs to be acquired - how to find value of expression. Many reach a deadlock, after all how many years passed since that moment how we studied in 3-5 classes? A lot of things were already forgotten, and something did not study. Rules of mathematical actions – are simple and you easily remember them. Let's begin with the bases that such mathematical expression. ## Expression definitionMathematical expression – set of numbers, signs of actions (=, +, - *,/), brackets, variables. Briefly is a formula which value will need to be found. Such formulas just meet it is aware of mathematics from school, and then pursue also students who chose for themselves the specialties connected with the exact sciences. Mathematical expressions are divided on trigonometrical, algebraic and so on, we will not run in "jungle". ## Practical recommendationsWhen finding value of expression we recommend to take the following advice: - Do any calculations at first on a draft copy, and after copy in a workbook. Thus you will avoid excess deletions and dirt;
- Count total of mathematical actions which will need to be executed in expression. Pay attention that according to rules, actions in brackets, then division and multiplication and right at the end subtraction and addition are carried out in the beginning. We recommend to allocate all actions with a pencil and to put figures over actions as sequence of their performance. In this case and to you and the child it will be easier to orient;
- Start making calculations strictly adhering to an order of performance of actions. Let the child if calculation simple, tries to carry out it in mind if it is difficult, put a pencil the figure corresponding to serial number of expression and carry out calculation in writing under a formula;
- As a rule, it is possible to find value of simple expression if all calculations are executed according to rules and the correct order. The majority face a problem at this stage of finding of value of expression therefore be attentive and do not make mistakes;
- Forbid the calculator. Mathematical formulas and tasks in life of the child maybe will not be useful to yours, but not in it the purpose of studying of a subject. The main thing – development logical thinking. If to use calculators, the meaning of all will be lost;
- Your task as parent – not to solve a problem for the child, and to help it with it, to direct. Let him make all calculations, and you watch that it did not make mistakes, explain why it is necessary to do so, but not differently.
- After the response to expression is found, write down it after the sign "=";
- Open the last page of the textbook on mathematics. Usually, there are answers under each exercise in the book. It does not prevent to be verified, whether truly everything is counted.
To find value of expression – on the one hand, simple procedure, the main thing to remember the basic rules which we passed in a school course of mathematics. However, on the other hand, when you need to help the kid to cope with formulas and the solution of tasks, the question becomes complicated. After all you now not the pupil, but the teacher and on your shoulders lies future Einstein's education. We hope that our article helped you to find the answer to a question how to find value of expression, and you with ease get to the core of any formula! |
