BODMAS stands for Bracket, Of, Division, Multiplication, Addition and Subtraction. In specific regions, PEDMAS (Parentheses, Exponents, Division, Multiplication, Addition and Subtraction) is the synonym of BODMAS.

Let try to understand it in simple language.   

Let take an example

 3 + ( 6 + 12 ÷ 3 ) × 4 - 7 × 8

How you solve this problem? The student who doesn't know about this rule confuse about how he started to solve this problem. 

Many students solve this problem in a straight way like. First, he adds 3 with 6 and then with 12 and then divide it with three then multiply it with four then subtract seven from it and finally multiply it with 8 and at last he got the answer 168. So, is the answer right? How he decides which operation is implied first and follow on. 

To clarify following doubts about the use of operation and how to start solving such problem BODMAS rule is given. 

In this question first, we have to solve the bracket and open it. Let take the bracketed value. There are two Operations there. First as given in BODMAS rule we have to use divide operation 12 ÷ 3 = 4 then we have to add it with 6; 6 + 4 = 10. Now open the bracket we have the equation 

3 + 10 × 4 - 7 × 8

Now according to BODMAS first we solve the multiplication operation. Thus 10 × 4 = 40 and 7 × 8 = 56. Thus we get an equation 

3 + 40 - 56  Now let add 3 with and 40 and subtract 56 from it. Finally, we get -13 as our answer.

Now I hope you must understand the BODMAS rule.

Thanks have a beautiful day!!

Q. Sum of two numbers is 95. If one exceeds the other by 15, find the numbers. Ans: Let One number be X. Therefore , the other number will be X+15. According to the question, X+X+15= 95 or, 2X+15=95 or, 2X=(95-15) or, 2X= 80 or, X= 40 So one number is 40. And the another number is (40+15)=55... read more

Q. Sum of two numbers is 95. If one exceeds the other by 15, find the numbers.

Ans:

Let One number be X. Therefore , the other number will be X+15.

According to the question,

X+X+15= 95

or, 2X+15=95

or, 2X=(95-15)

or, 2X= 80

or, X= 40

So one number is 40. And the another number is (40+15)=55.

Flower is the reproductive organ of a plant. A flower may be a monoecious or dioecious, depending on whether the flower has either male or female organ or both the organs respectively. The female organ is known as the Gynaecium and the male organ is known as the Androecium. The female organ consists of the carpel, style and the stigma. The male organ includes stamens and anthers. The carpel is oval shaped and  contains the ovary,which further consists of the female gametes. The style is a stalk-like structure, which helps in transporting the pollen grains landed on the stigma to reach the ovules. The stamen is again a feathery stalk-like structure which holds the anther or box-like structure. Anthers contains the pollem grains or the male gametes,inside the pollen sacs. Most flowers are bright and showy and give nectar and sweet smell to attract insects for pollination. In return of the honey,the insects spread the pollen grains. The transfer of pollen grains from the anther of a flower to the stigma of another flower is known as pollination. Pollination can be of two types:Self and Cross. Self pollination occurs either between the anther and stigma of the same flower or of a different flower on the same plant. Cross Pollination occurs between the stigma of one flower and anther of another flower on 2 different plants. Pollination can occur in insects, wind, water, and animals and can take place both by naturally and by artificial means. Natural Pollination can occur only between the plants which are genetically similar to each other. The fusion of male gametes and female gametes is known as sexual reproduction.
