Ranges of numbers

Friends, today i have come up with some simple sample examples of ranges of numbers below. I had discussed various numbers till date like i had worked on problems of complex numbers and many more such numbers. Lets look at this concept today.

There two steps that has to be followed to find the ranges of numbers.

Firstly set of numbers given has to be arranged in ascending order that is lowest number to the highest number. Next and final step is subtracting the higher number with the lower number.

Let me discuss a few sample example here.

Example 1:- Find the range of set of numbers: { 52, 44, 27, 30, 62, 12, 55, 70}

Now the first step of arranging the set into ascending order
{12, 27, 30, 44, 52, 55, 62, 70}

Now the second step of subtracting the lower number to the higher number
70-12= 60

Therefore the answer is 60.

I have explained this example using perfect steps that is needed. I am actually want to work on 6th grade math problems, if you have any problem in any topic let me know and i will get back to you.

Simple math word problem

When i was explaining the importance of water to my daughter, friends she had endless questions which i had to answer. Not only on science, she also asked me about math, English and almost all the subjects.

She wanted to know why is railway line said to be parallel lines. I had to explain her the details with a diagram. But she is too small to learn this but i appreciate her enthusiasm in learning new things.

She wanted to know learn how to add, i gave her some simple examples like...the apple example

You have two apples with you and i have two so count how many do we have in total.
She started counting with her tiny fingers 2+2=4

She shouted " Mom totally we have 4 apples".

Then i told her that this is the additional property of mathematics.

She wanted to learn more but then i stopped at this and asked her to have her dinner and go to sleep. Once she went to sleep, i started hunting for some math problems online which i can explain her as per age and i was preparing myself for the next session with my daughter.

blank venn diagram

What is blank Venn diagram guys? I will define what is Venn diagram here below.

Venn diagram is victimized for solving the difficulty easily by viewing guiltless represented content. This Logician diagram template was the gear mortal to settle the problem using this Venn plot guide. By using this guide, we can simplify the job and can translate the problem understandably. The blank Venn diagram means no data updated in the Venn diagram.

In this blank Venn diagram is of following types.

1. Venn diagram
2. Venn diagram with lines
3. Tri-Venn diagram

You will enjoy the concept only after you start working on it. Believe me guys, its awesome. A Venn diagram has two sets of elements. Each circle explains a set. Elements are the sets which common is represented by the intersection part of the Venn diagram, it helps on math which i think all of us need it.

why are geometry symbols important

This post is going to be a very useful post for all of us. Looking at the topic itself you can see that the topic of the day is why are geometry symbols important. I have discussed with you the importance of geometrical instruments earlier.

Now for instance you are given a square and asked you to find the length, how would you find the length if the corners are not named (a, b, c, d) that is not possible therefore these letters represents the corners of the square. In a line the numbers and letters are used to identify the pointer.

How about the parallel line, we use the symbol //, what if i say a is // to b you will be able to make out what this sentence mean, it says that a is parallel to b here.

The symbols are used to identify something implicit meaning, they give a short meanings for shapes and terms.

Guys therefore geometry symbols are very important. The parallelogram shapes can also be shown using symbols.

Some algebra problem

Here below i have answers to math problems, look at these problems and look at the steps used to solve these problems. I have already worked on 5th grade math problems earlier.


Question 1:

x - 7 = 20

Solution:

Adding 7 on both sides,

x - 7 + 7 = 20 + 7

x = 20 + 7

x = 27

Question 2 ( algebra word problem)

A number n times 3 is equal to 120.

This is an easy one. The word 'times' says you that you must multiply the variable n by 3, and that the result is equal to 120. The equation can be written as below.

3n = 120

I will come back again with some interesting topic again, Lets learn precalculus formulas in our coming post.

Math help received

You have a problem solving mathematics don't worry. You children don't have to worry these days. Like for instance a 9th grade math student is in between a tough topic, he/she can work on it easily.

If you need any topic or you are in between any homework for any subject, these days you get help. There is nothing called impossible these days. Today's technology help us so much that i really appreciate the help we get it from them.

I am looking for vector geometry at the moment and i am sure will be able to discuss the concept with you shortly.

The prime numbers

We learn t what are the prime numbers earlier. We have worked on various problem on prime numbers, look for the list of prime numbers below.

Look at the prime numbers from 2 to 10.

The number 2 is exactly divisible by 2 and 1.

The number 3 is exactly divisible by 3 and 1.

The number 4 is exactly divisible by 4, 2 and 1.

The number 5 is exactly divisible by 5 and 1.

The number 6 is exactly divisible by 6, 3, 2 and 1.

The number 7 is exactly divisible by 7 and 1.

The number 8 is exactly divisible by 8, 4, 2 and 1.

The number 9 is exactly divisible by 9,3 and 1.

The number 10 is exactly divisible by 10, 5, 2 and 1.

The numbers 4, 6, 8, 9, 10 are having more than 2 factors

The numbers 2, 3, 5, 7 are having exactly two factors, say 1 and the same number. Such numbers are called as prime numbers.

Observe the list prime numbers above.
