Question

My friend doesn't understand this equation and %100 sure that she knows the right answer:

48÷2(9+3) =

Go, Mathbro's, show her your knowledge.

Answer 1

She should know the rule of VBODMAS

Answer 2

First solve verniculum, then bracket, then off, then division, then multiplication, then addition and at last subtraction

Answer 3

Give it a shot.

Answer 4

See,

first in this question

what is first bracket

Answer 5

i think you mean vinculum. the thingy like \(\overline{x+3}\)

Answer 6

solve what is in the bracket

Answer 7

so 9+3 = 12

Answer 8

Yes @lgbasallote

Answer 9

So, the equation becomes
48 / 12

Answer 10

Now what is left is division

so divide 48 by 12
u get 4 which is ur answer

Answer 11

Got that @Compassionate

Answer 12

you forgot the 2

Answer 13

Woops sorry

Answer 14

48÷2(9+3)
48÷2(9+3)
24 (9 + 3)
24 x 12
288

Answer 15

interesting is if you would do it like \[\frac{48}{2(9+3)}\]ir\[\frac{48}{2}(9+3)\]

Answer 16

Yes
because division comes first

Answer 17

@lgbasallote when the question is given in the format @Compassionate has given then we use the VBODMAS rule to clear all such doubts

Answer 18

shouldnt it be VBBPMAS

Answer 19

there isnt a mathematical operation "off" is there?

Answer 20

Yes there is

Answer 21

oh exponent

Answer 22

I meant "of"

Answer 23

Nope

Answer 24

well you dont have exponent in your "VBODMAS"

Answer 25

I meant yes for exponents and nope for your comment that there doesn't exist any

Answer 26

Now it begins.

Answer 27

@lgbasallote of is for exponents

Answer 28

that's an odd way of putting it lol

Answer 29

Which problem are we solving here people? Hello? \[\frac{ 48 }{ 2(9+3) } or \frac{ 48 }{ 2 }(9+3)\]

Answer 30

Also consider which answer is harder to get a whole number for? The one with an answer of 2 or 288? Generally problems are made.

Answer 31

@Kainui what if the same question comes in your exam........ u r not going to write that what do u mean to say................
to remove such problems the rule of VBODMAS is followed

Answer 32

The rule IS followed. What you have to understand is that the left answer is correct. When I wrote it like that it becomes immediately obvious why.

See in the left formula you have 2(9+3) whereas in the right formula it is interpreted as .5(9+3) which is clearly wrong.

So to clarify, 2 is the correct answer.
