WORKING WITH PRIME NUMBERS

Prime Numbers are studied under Arithmetic under Math. The Number system is classified into different types based on their properties as:
  • Whole Numbers
  • Natural Numbers
  • Rational and Irrational numbers
  • Integers
  • Prime Numbers
Prime Numbers are a type of numbers discussed here. Prime Numbers are those numbers which are divisible only by themselves and 1. For example :13 is only divisible by itself and 1.
In other words, prime Numbers are those which do not have any other factors apart from themselves and 1.

Prime numbers have the following characteristics:
  • 2 is the only Prime number
  • 0 and 1 cannot be considered as Prime numbers
  • A number ending with 5 or 0 is never prime as it is divisible by 5.
Students have to learn to differentiate between the kinds of numbers. The prime numbers are often used in finding Prime factors of a number(Prime factorization). Students should also learn about divisibility and the rules of divisibility.

Fraction Siplifier

Fraction simplifier

The fraction 12/64 is not reduced to lowest terms.

We can simplify this fraction to lowest terms by dividing both the numerator and denominator by 4.

Why divide by 4? 4 is the Greatest Common Divisor (GCD)
or Greatest Common Factor (GCF) of the numbers 12 and 64.

So, this fraction reduced to lowest terms is3/16

The final answer is 3/16

There are several types of lines in math. Here we are giving some important lines only. Types of lines can be classified into following types:
  • Straight lines,
  • Vertical line (perpendicular),
  • Horizontal line (parallel),
  • Dotted lines,
  • Dashed lines,
  • Zigzag lines (waye lines),
  • Curved lines and etc…

Here we are going to explain about 5 important types of lines only.

Example problem 2:- using to solving the math help of equations

Evaluate: 10x + 8y– 7y + 10x + 4y = 0

Solution:

Step 1: Group together the like terms:

10x + 8y – 7y + 10x + 4y = 0
(10x + 10x) + (8y – 7y + 4y) = 0

Step 2:

20x +5y = 0

Answer: 20x +5y = 0

A Line Plot

A line plot example
A line plot is used to shows data on the number line with x or marks to show the frequency of data. That means measure the frequency of an item in a given set of data. The relate terms for line plot are number line, data and frequency. A line plot is shows frequency of data along a number line. It is a quick and easy way to organize data. In this article we discuss about choose line plot.

Steps to Solve Choose Line Plot:

Step 1: First arrange the data items from minimum value to highest value.

Step 2: Then grouping the data that are the same value.

Step 3: Match the grouped data with the figures shown.
