Mixed fractions


Let's learn about mixed fractions and subtracting mixed fractions in today's learning.

Mixed fractions are those fractions which are formed of a whole number and a fraction. In order to subtract mixed fractions, we need to first convert the mixed fractions to improper fractions and then use the same method of subtract fractions. Below are the steps of subtracting mixed fractions:

Step 1) Convert mixed to improper fraction.
Step 2) If denominators are different, find the LCM and take a common denominator.
Step 3) Subtract the numerators.

probability examples


In this blog we will learn about probability examples,
Ex 1: What is the probability of getting a sum is 4 or 8 when throwing two dice simultaneously?
Solution:Now we will see how to solve probability examples
Let S = sample space, S = {(1, 1), (1, 2), (1,3)...(6, 5), (6, 6)}, n(S) = 36
A be the event of getting a sum is 4, n(A) = {(1, 3), (2, 2), (3, 1)} = 3
B be the event of getting a sum is 8, n(B) = {(2, 6), (3, 5), (4, 4), (5, 3), (6, 2)} = 5
P(A) = =
P(B) = =
P(A or B) = P(A) + P(B)
P(4 or 8) = + = .
In the next blog we will learn about linear definition and math dictionary algebra.Hope you like the above example of probability examples,please leave your comments if you have any doubts.

square root of 72


In this blog we will learn how to solve square rot of 72,

How to Solve Square Root of 72:

In this given number square root of 72 is written as in the form of .
It can be solve by so many methods and operations like addition, multiplications and etc…
And the number 72 is factored by so many numbers like 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, and 36.
Now we have to solve the given number square root of 72 in all the entire methods of one by one.
If we solve the square root of 72, we get the constant answer or exact value is 8.48. But it is formed by so many ways, now we are find the answer for square root of 72 in so many ways.It is also easy to find square roots of other numbers like say for example we can learn about solving square root of 256 . In the next blog we will learn about percentage change calculator.Hope you like the above example of square root of 72,please leave your comments if you have any doubts.

factor theorem


In this blog let us learn about factor theorem,

Proof of Factor Theorem:In this blog we will learn about factor theorem,

P(x) is divided by x-a,
Using remainder theorem,
R = p (a)
P(x) = (x-a).q(x) + p(a)
But p (a) = 0 is given.
Hence p(x) = (x-a).q(x)
(x-a) is the factor of p(x)
Conversely if x-a is a factor of p(x) then p(a)=0.
P(x) = (x-a).q(x) + R
If (x-a) is a factor then the remainder is zero (x-a divides p(x)
Exactly)
R=0
By remainder theorem, R = p (a) .Next let us learn about area of a circle formula,in the next blog we will learn about math definitions for kids.Hope you like the above example of factor theorem,please leave your comments if you have any doubts.

triangles and angles


In this blog we will learn about triangles and angles, Triangle is one of the basic shape in geometry, and it is a closed figure with three sides. There are different types of triangles available and can be categorized based on their sides and angles.Three types of triangle, it is classified based on their sides and four types of triangles based on their angles.Let us discuss about three basic types of triangle; it is classified based on their sides.
Classifying triangles based on their Sides.
1) Equilateral triangle
2)Isosceles Triangle
3) Scalene Triangle,Normally angle is the shape in the geometry. They are special forms of the angle is obtainable in the mathematic. These special forms of the angle are specified below,right angle,acute,obtuse,straight,reflex and complete angles.In the next blog we will learn about probability definition and equations in algebra.Hope you like the above example of triangles and angles,please leave your comments if you have any doubts.
