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.

When somebody ask you define polygon will you be able to define them with some examples. I had just defined what is a polygon and what are its properties. You all should be able to explain them, explain them with some examples.
I also explained you the different types of polygon with some examples. You can explain them with the help of some diagram also.
Show them the four sided shapes and explain them....

Few math exams tips
This is my first post in this blog, i just want to give you some of the tips that you can use for your math examination.
Guys work on more and more problems and once you have done it check your math answers online so that you come to know where you have gone wrong and correct yourself. Be very careful when you write, your handwriting has to be very clear. The numbers which are written by you should be very clear.
Write step by step when you solve some problem. You have old free exams papers, get that from your old friends or your seniors and start working on it. If you are not getting any answers for some problem either you ask your teachers, parents, friends or look for some home work help which we get online. All the best for your exams....
