Mathematical Expression

In mathematical, an expression is a finite combination of symbols that are well-formed according to the rules applicable in the context at hand. In mathematical, symbols can designate values, variables, operations, relations, or can constitute punctuation.

         In mathematical, an expression may be used to designate a value. In mathematical, which value might depend on values assigned to variables occurring in the expression; the determination of this value depends on the semantics attached to the symbols of the expression.

Basic natural law for mathematical expression:

        In elementary algebra, we list the fundamental rules and properties of pre-algebra and give examples on they may be used natural law.

        Suppose that a, b and c are variables or mathematical expressions using natural law.

1. Commutative Property of Addition In mathematical.

           a + b = b + a

 2. Commutative Property of Multiplication In mathematical.

           a * b = b * a

3. Associative Property of Addition In mathematical.

       (a + b) + c = a + (b + c)

4. Associative Property of Multiplication In mathematical.

          (a * b) * c = a * (b * c)

5. Distributive Properties of Addition Over Multiplication In mathematical.

         a * (b + c) = a * b + a * c
    and
        (a + b) * c = a * c + b * c

Steps for simplify the mathematical expression:

            Step 1: Group the terms containing the same variable together in algebra expressions using natural law.

            Step 2: Perform the operation inside the parentheses for the variable and other.

            Step 3: Rewrite the expressions and simplifying the algebra expressions.

            Step 4: To check the equation, if there is able to simplify the expression, then repeat the step 1 to 4.

Example problems for simplify the mathematical expression using natural law:

        In mathematical expressions, find the value of x using natural law.

              3x(1x+4x²)

Solution:

            A(B+C)=AB+AC

            Step 1: is to determine what terms represent A,B and C in the given equation.

                        A represents 3x.

                        B represents 1x.

                        C represents 4x^x.

            Step 2: is to perform the multiplication operation.

                        AB=3x(1x)=3x²

                        AC=3x(4x²)=12x³

            Step 3: is to rewrite the problem.

                        3x(1x+4x)=3x²+12x³

            Step 4: is to simplify the answer.

                        3x²+12x³=0

                                 12x³=-3x²

                                                12x=-3

                                        x=`-1/4`

                 The answer is x=`-1/4`.
