Question

A very important tutorial on the VBODMAS rule

Answer 1

THE VBODMAS RULE

Answer 2

'VBODMAS' (Vinculum - Bracket - Of - Division - Multiplication - Addition - Subtraction) rule should be applied for solving problems involving one or more mathematical operations like multiplication, division, addition, subtraction etc. Such problems are solved in the order of vinculum, bracket, of, division, multiplication, addition and subtraction. Remember 'Of' in VBODMAS means multiplication.

Answer 3

also don't copy paste

Answer 4

it is considered as plagiarism ..

mention the link also @vishweshshrimali5

Answer 5

The VBODMAS rule is used to solve the equations which are not so in use

Answer 6

I will @mathslover .

Answer 7

do that

Answer 8

This rule is really only useful in knowing what to do in the case of something like

\[\frac{ 5x }{ 3 }=2\] so that you know to multiply 3 to both sides and then divide out the 5. I think you're taking this too far vish lol.

Answer 10

As @Kainui also said ..... about \(\div\) sign........ CORRECT....... in the older times it was used. but now it has gone....... but I think it is important to have some knowledge about old things...... also

SO here I go

Answer 11

@Kainui I am not doing to prove you wrong....... I just want to increase the knowledge of everyone

Answer 12

The VBODMAS rule states that whenever more that algebric operations are involved then First one should solve Vinculum , then solve what is in brackets, then of operation, then division, multiplication , addition and at last subtraction

Answer 13

It would be better if we use some examples to understand it

Answer 14

I would use the material from here

u can even try them yourself

Answer 15

1. 45 - 4 x 6 - 5 + 14 \(\div\) 7 = ?

Answer 16

So, according to VBODMAS rule
we should solve division first

Answer 17

so
14\(\div\) 7 = 2

Answer 18

equation remains

45 - 4 x 6 - 5 + 2

now solve multiplication
so
4x6 = 24

Answer 19

now what remains
45 - 24 - 5 + 2

now use addition

45 +2 = 47

so what remains

47 - 24 - 5

now solve we get

answer = 18

Answer 20

now some users said that I didn't mention question correctly

Answer 21

So, lets understand the meaning of 21\(\div\)3(10-3)

Answer 22

and next some users will say please mention right link ... haha jk

Answer 23

thanks a lot for this tutorial

Answer 24

Please don't interrupt @mathslover u will get the time for that too

Answer 25

I have right to interrupt..

Answer 26

so,

21\(\div\) 3 (10-3) = \(\cfrac{21}{3}(10-3)\)

Answer 27

right

Answer 28

and u may ask why ?

just because of the same rule VBODMAS

Answer 29

We had to solve bracket first

Answer 30

we would get
10 - 3 = 7

Answer 31

right

Answer 32

Now do we have to solve division first or multiplication
obviously
division first
so

Answer 33

It's very inconsistent to use the form (x)(y) with ÷.

You should use (x)(y) and x/y together or x*y and x÷y together. Mixing the too together causes confusion and wastes everyone's time.

Answer 34

\[\cfrac{21}{3}\]

Answer 35

very right @Kainui

Answer 36

that makes the whole diff.

Answer 37

@Kainui I know that......... but I never created those signs.......We should know their meaning when they stand for one of the algebric operation division

Answer 38

So now we all can solve question no. 3 also.......... Can we ?

Answer 39

I don't think most of the people would have troubles with these equations:

21÷ 3 * (10-3)

or \[\frac{ 21 }{ 3 } (10-3)\]

Answer 40

@Kainui if a sadistic professor would like to fail his students by confusing them using this thing, then this is worth knowing isn't it?

Answer 41

the BODMAS rule has no significance after one reaches a certain maturity level..only the brackets matter then !

Answer 42

oh believe me @shubhamsrg it's more useful than you think. if it isn't useful for you then maybe you havent learned it enough?

Answer 43

\[\int\limits_{1}^{10}21÷ 3(10-3)dx\]

Answer 44

ahh,,can you show me any example which proves me wrong??

Answer 45

@shubhamsrg there's your example, solve the integral lol.

Answer 46

bracket first,,so its
21 / 3*7
how does it matter whether you multiply or divide first here!!

Answer 47

If you divide first you get 49, if you mulitply first you get 1.

Answer 48

\[3\div2\times4=?\]

Answer 49

thats where brackets come into play..
any expression like that will assume it to be 21 / (3*7)

same thing as 2+2/2 ..some might say ans is 2,,some 3 ..

Answer 50

these ques are good for lower classes..after a certain time,,one can certainly argue that expression is insufficient due to lack of brackets..

Answer 51

Time to stick a fork in this topic, it's done.

Answer 52

what is \[3\div2\times4=?\]

Answer 53

you cant predict really,,altough we will have to assume it (3/2) *4
hmm..

Answer 54

leaves 6 ..

Answer 55

but i wont say 3/8 is wrong..

Answer 56

huh, ? but D comes before M in

VBODMAS

Answer 57

is VBODMAS a rule ?

Answer 58

I don't want to comment anymore on this topic..........

Answer 59

oh @vishweshshrimali5 was right .... I was wrong there

sorry @vishweshshrimali5 for arguing you.
