How to teach division

Introduction to how to teach division for kid:
In mathematics, especially in elementary arithmetics, division (÷) is the arithmetic operation that is the inverse of multiplication. Specifically, if c times b equals a, written: c x b =a. Where b is not zero, then a divided by b equals c, written: a/b =c.
For instance, 6/3 = 2, since 2 x 3 =6. In the above expression, a is called the dividend, b the divisor and c the quotient. This could also help us on fractions in simplest form

Help with polynomial function

Introduction polynomials and polynomial function:
Hear is and brief introduction on Polynomials and Polynomial Functions.An Algebraic expression of the form axn is called a monomial in x, where a is a known number, x is a variable and n is a non-negative integer. The coefficient of yn and n has a number, the degree of the monomial. For example, 7x3 is a monomial in x of degree 3 and 7 is the coefficient of x3. The total value of 2 monomial is known as a binomial and the sum of three monomial is called a trinomial.
Following is the sample exercise on polynomial and polynomials function.

Simplifying Equations

Introduction to simplify equations:
In this article let me help you on simplifying equations. An equation is defined as the the equality of two expressions which consists of variables and constants. Equations consist of the expressions that is to be equal to the opposite sides of an equal sign.

The following rules are used to simplify the equations and the equation does not change.
1) Add or subtract any variable or numbers to the both sides of the equation.
2) Multiply or divide any variable or numbers to the both sides of the equation.

Examples of equation: m+10=14, x+22=11, x+25=1,….
Now, we are going to see some of the simplifying equations problems.
Simplifying Equations Problems:

Example problem 1:
Simplify the equation: 7 x + 7 = 91

Solution:
Subtract 7 on both sides of the equation
7x + 7 - 7 = 91 – 7
7x = 84
Divide by 7 on both sides of the equation. This could also help us on area of a quadrilateral
7x / 7 = 84 / 7
x = 12
So, the simplified answer is x = 12.

In this article let me help you on statistics problems solved. Since we had studied enough on statistics let me help you with the sample problems.

Following is the sample problem on statistics:

Problem 1

For boys, the average number of absences in the first grade is 15 with a standard deviation of 7; for girls, the average number of absences is 10 with a standard deviation of 6.

sample?

(A) 0.025
(B) 0.035
(C) 0.045
(D) 0.055
(E) None of the above
Solution

The correct answer is B. The solution involves four steps. This could also help us on statistics answers online
* Find the mean difference (male absences minus female absences) in the population.
μd = μ1 - μ2 = 15 - 10 = 5

* Find the standard deviation of the difference.
σd = sqrt( σ12 / n1 + σ22 / n2 )
σd = sqrt(72/100 + 62/50) = sqrt(49/100 + 36/50) = sqrt(0.49 + .72) = sqrt(1.21) = 1.1

* Find the z-score that produced when boys have three more days of absences than girls. When boys have three more days of absences, the number of male absences minus female absences is three. And the associated z-score is
z = (x - μ)/σ = (3 - 5)/1.1 = -2/1.1 = -1.818


Therefore, the probability that the difference between samples will be no more than 3 days is 0.035.

Circumference of a Circle Formula

Introduction:

In this section let me help you on circumference of a circle formula. The circle is a shape with points the same distance from the center.

It is named by the center.

The circle to the left is called circle X since the center is at point X

If you measure the distance around a circle and dividing the distance across the circle through the center point, you will always come close to a particular measurement, depending upon the accuracy of your value.

This value is approximately 3.141592653589... We use the Greek letter (pronounced pi) to represent the value.

The distance around a circle is called the circumference. The distance across a circle through the center point is called diameter. (Pi) is the ratio of the circumference of the circle is called diameter.This could also help us on examples of personification

Thus, for any circle, if you dividing the circumference by the diameter, you get a value close to (pi)

The radius of a circle is a distance from the circle center point of a circle to any point on the circle.
