convert 1 pound in dollars

Lets work some simple word problem to convert 1 pound in dollars below. We learn t how to convert 1 million to thousands earlier, does any body remember

If you are in United States of America .But you are from England. You get it in 350 pounds. If you are a visitor to England and to go to a nearby shopping center to buy a wine and you get to know the rate of wine is 200 dollars . how many dollars would you give to the shop keeper?

Solution:

Formula for converting pounds to dollar

1 pound 1.51 dollars

Multiplied by 350 for both sides

350 pounds 528.5 dollars

Now you give 350 pounds to shopper.

528.5 - 200 dollars = 328.5 dollars converted into pounds.

They will return to 328.5 dollars.

Answer:

The shopper gives to 328.5 USD.

Will come back again with some more interesting topic friends, until then keep smiling and let me know your comments on this. How about discussing on formula circumference of a circle shortly, do you like this idea?

Formula for conditional probability

I have worked on probability functions many times till date. We also had a conditional probability quiz too? Did you see that? Did you guys work on it?

Here below i have a formula which will help you learn conditional probability.




Get prepared with some sample problems and i will come back with some more questions on this. Guys i came across a site which helped me in unit circle trigonometry try it out.

composite numbers 1-100

Friends do you know composite numbers 1-100 come on, can any body tell me those numbers? I have discussed on various numbers such as prime numbers, whole numbers and i have also briefed you with what is composite numbers.

Guys to learn composite numbers 1-100 we need to know what does composite number mean actually.

Composite numbers:- The numbers which can be divided by more than 1 but number except 1 and the number itself.

Composite numbers 1-100 are as shown below.

4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30,32,33,34,35,36,38,39,40,42,44,45,46,48,49,50,51,52,54,55,56,57,58,60,

factors of 80

Lets discuss what are the factors of 80 below. We have discussed a similar topic earlier also, like the factors of 49, factors of 39 and many more.

Factors of 80------> 1 2 4 5 8 10 16 20 40 and 80

We have worked on various other topics in mathematics and we have also found what are the factors of various numbers earlier. Now lets see what are the factors of 72 below.

Factors of 72-------> 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.

Do you have any specific topic that you want me to discuss with you..keep me informed and i would help you out.

A lovely online math help

Guys i never knew the names of polygons earlier. When i first wrote about the definition of a polygon, i was really confused about it. But wanted to learn more...so decided to learn geometry as soon as possible. I took some help online and started learning it. I learn t different types of polygon and i have shared many with you guys also.

I came across so many definitions in geometry that i couldn't believe myself. Today i can teach my little daughter today, i thank the latest technology.

Now i am with volume measurement, i found that also very interesting and waiting to share it with you guys....:-)..

math fun

When i saw teachers teaching their students addition color by number, an idea struck my mind.
I felt that also can be a part of enjoying math while we learn or teach. It will also help in understanding the math symbols perfectly.

Children of class 2 or 3 are very innocent and will not enjoy numbers as much as children of 8 or 9. I have a feeling that we can teach children by filling colors to the numbers and ask them to colour the next few figures and ask them to count those colored figures and teach them how to subtract with this coloured figures. A beautiful concept

This concept can be used even for addition as well. Guys try doing that. I think famous math people also learn t math by make math fun.

area of pentagon

Lets learn what is the formula to calculate area of pentagon below.



Look here on top, we see what is the formula to find the area of a pentagon, use this formula and start solving problems which you come across.

I was thinking of discussing even function in my next post, do you like the topic??

formula of triangle

When we discuss on calculating triangle, we need to know what are the formula of triangle before we start. This is what i want to discuss with you guys today.

Formula for a Triangle:

Area of triangle = ½(Base *height),

Perimeter of triangle= (sum of three sides) = (a + b + c)

Use these formulas and calculate any problem with triangle. I am sure this post is very useful to you all. Give me your comments.

I have another important post which i posted a few days back called algebra math problems, check that out...

Statistics answer

What is statistics guys? I can explain it to you in one single sentence, in a very simple sentence. It is Statistics is defined as “Numerical data collected systematically, summarized, and tabulated”.It deals with grouping of data.

We have many statistics problems online look into it and start solving those problems. Well if you have been given some statistics problem in school work on it first, try getting the answer by yourself and after you have got the answer, look for free statistics answers and check if your answers are right.

Not only statistics, you can refer to these online sites to check if your homework or the problem you have been working is right by looking into sites for those particular subject. I have taken a similar help in online trigonometry help, i worked on my homework and checked if my homework was done perfectly.
