How to find the meaning of an expression: tips and tricks
You, as parents, in the process of teaching yourchild, you will often come across the need to help with solving domestic problems in mathematics, algebra and geometry. And one of the basic skills that must be learned is how to find the meaning of an expression. Many come to a dead end, because how many years have passed since the moment we studied in grades 3-5? Much has already been forgotten, but something has not learned. The very rules of mathematical actions are simple and you can easily remember them. Let's start with the basics of what a mathematical expression is.
Definition of expression
A mathematical expression is a collection of numbers,signs of actions (=, +, -, *, /), parentheses, variables. Briefly - this is a formula, the meaning of which will need to be found. Such formulas just meet in the course of mathematics from school, and then persecute and students who have chosen for themselves specialties related to the exact sciences. Mathematical expressions are divided into trigonometric, algebraic and so on, we will not run into the very "jungle".
Practical recommendations
When finding the value of an expression, we recommend using the following tips:
Do any calculations first on the draft, and then rewrite it in the workbook. Thus you will avoid unnecessary strikes and dirt;
Recalculate the total number of mathematicalactions to be performed in the expression. Note that according to the rules, the actions in parentheses are performed first, then division and multiplication, and at the very end, subtraction and addition. We recommend that you select all the actions with a pencil and put the numbers over the actions in order of priority. In this case, both you and the child will be easier to navigate;
Begin to make calculations strictlyadhering to the order of performance of actions. Let the child, if the calculation is simple, tries to do it in the mind, if it is difficult, then put a number corresponding to the serial number of the expression with a pencil and perform the calculation in writing under the formula;
As a rule, to find the value of a simple expression is notis labor if all calculations are performed in accordance with the rules and the correct order. Most people face the problem at this stage of finding the meaning of the expression, so be careful and do not make mistakes;
Prohibit the calculator. The mathematical formulas and tasks in the life of your child may not be useful, but this is not the purpose of studying the subject. The main thing is the development of logical thinking. If you use calculators, the meaning of everything will be lost;
Your task as a parent is not to decide for a childtasks, but to help him in this, to direct. Let him make all the calculations himself, and you make sure that he does not make mistakes, explain why it is necessary to do so, and not otherwise.
After the answer to the expression is found, write it after the "=" sign;
Open the last page of the mathematics textbook. Usually, there are answers for every exercise in the book. Do not interfere to check whether everything is counted correctly.
Find the meaning of the expression - on the one hand,a simple procedure, the main thing to remember the basic rules that we took in the school course of mathematics. However, on the other hand, when you need to help your child cope with formulas and problem solving, the question becomes more complicated. After all, you are no longer a pupil, and the teacher and on your shoulders are the upbringing of the future of Einstein.
We hope that our article helped you to find the answer to the question of how to find the meaning of the expression, and you can easily figure out any formula!
