what is bodmas?

Question

j.w cus ikno iv done it but cant remember what it is?

Answer 1

BODMAS is the secret code which enables us to know exactly the right sequence of doing things mathematically. In particular electronic calculators have to use a rule (known in computing circles as an algorithm) to know which answer to calculate when given a string of numbers to add, subtract, multiply, divide etc.

What do you think the answer to 2 + 3 x 5 is?

Is it (2 + 3) x 5 = 5 x 5 = 25 ?

or 2 + (3 x 5) = 2 + 15 = 17 ?

BODMAS can come to the rescue and give us rules to follow so that we always get the right answer:

(B)rackets

(O)rder

(D)ivision

(M)ultiplication

(A)ddition

(S)ubtraction

According to BODMAS, multiplication should always be done before addition, therefore 17 is actually the correct answer according to BODMAS and will also be the answer which your calculator will give if you type in 2 + 3 x 5 .

I am assuming that you know what everything in BODMAS means apart from "Order". Order is actually a poor word to use here "Power" would be much better though BPDMAS doesn't quite have the same ring to it!

Order means anything raised to the power of a number.

You may have heard of Einstein's famous equation E = mc2 here it can be said that c is raised to the power 2, or c has order 2 or c is squared (they all mean the same thing!).

Here's an example to show how to use all the features of BODMAS:

Explain the answer that a calculator would give to the calculation 4 + 70/10 x (1 + 2)2 - 1 according to the BODMAS rules.

Brackets gives 4 + 70/10 x (3)2 - 1

Order gives 4 + 70/10 x 9 - 1

Division gives 4 + 7 x 9 - 1

Multiplication gives 4 + 63 - 1

Addition gives 67 - 1

Subtraction gives 66



THE PART OF BODMAS MOST OFTEN FORGOTTEN

It is quite common for people to forget that brackets always come first - which means you can calculate the answer of whatever is in the brackets before you attempt to calculate the rest of the problem.

Once you've worked out everything in the brackets, normally these sort of problems become very easy!

Answer 3

BODMAS is the secret code which enables us to know exactly the right sequence of doing things mathematically. In particular electronic calculators have to use a rule (known in computing circles as an algorithm) to know which answer to calculate when given a string of numbers to add, subtract, multiply, divide etc.

It stands for brackets off, divive and multiply, add and subtract.

Answer 4

Its the order in which to prosess in modern maths

Brackets Of Division Multiplication Addition Subtraction

Answer 5

Brackets - Other(Indices and such) - Division - Multiplication - Addition - Subtraction This is the order that aspects in a maths question should be dealt with

Answer 6

Bodmas is a government agency who's duty it is to keep students working hard in school so they don't rebel against the government and form their own super-intelligent nation state.

Answer 7

BODMAS

B = Brackets

O = Orders

D = Division

M = Multiplication

A = Addition

S = Subtraction

Answer 8

nicely, BODMAS is somewhat is a quick time era for Brackets, ability Of, branch, Multiplication, Addition and Substraction...that's used for fixing complications in mixed operations.....even pupils in common college extensively utilized this technique in recent times....this rule became used for extra beneficial than a decade in the past..

Answer 9

the order of doing mathematical operations

brackets

order ( i.e. powers, squares or indices)

division multiplication (can be done in either order)

additon subtraction (again in either order)

Answer 10

It's an acronym for remembering the right sequence of doing things mathematically. It stands for B(RACKETS, O(RDER, D(IVISION, M(ULTIPLICATION, A(DDITION, S(UBTRACTION.
