"How and when to apply "BODMAS RULE"?

                      BODMAS rule : How to apply

Before starting our today's topic, here I'm having an interesting question I hope this type of question might have crossed your eyes sometime, so let's check this out...

18  ? 12 ? 4 ? 5 = 59

sol.

18 × 12 ÷ 4 + 5 = 59

here in this solution we'll apply BODMAS rule in which first of all the brackets will be solved then orders, division then multiplication, Addition and then in the last subtraction

so first of all
(18 × 12 ÷ 4) will be solved
it will result in 54

then
54 + 5 = 59         QED (means QUIET EASILY DONE)


so today we have reached onto a topic i.e. BODMAS
to explain it more just check this image out

Always with this sequence all the questions to be solved similar to the above given one,

to put some more practice over this I'm having some more questions to explain let me share these :

Q. 8÷2(3+1)

Now solution will be 

8÷2(4)

4*4= 16.

Q.Evaluate this expression:

58 ( 2 + ( 89 ( 112 – 82 ) ) )

Solving this question using the priority of BODMAS, we get;

• First, the innermost bracket will be solved.

58 ( 2 + ( 89 * 30 ) ) // solving the innermost parenthesis

• 58 ( 2 + 2670 ) // Solving the next brackets, subsequently
• 58 ( 2672 ) // Multiplying to get the final result
• 154976

again one more question with solution is here 

1. 9900 – 68 of (214 -105) + 72 × 89

• 9900 – 68 of 109 + 72 × 89 // Simplifying ‘bracket’ 214 -105;
• 9900 – 68 * 109 +72 * 89 // Simplifying ‘of’
• 9900 – 7412 + 72 * 89 // Simplifying ‘ multiplication’ 68 * 109
• 9900 – 7412 + 6408 // Simplifying ‘ multiplication’ 72 * 89
• 2488 + 6408 // Simplifying ‘ subtraction’ 9900 – 7412
• 8896 // Simplifying ‘ addition’ 2488 + 6408

To make BODMAS a puppet of your hand you need to learn the priority order.

these are the generic Question usually asked in competition and civil exams and mostly in entrance examinations 

here are some of the questions I'm going to give you all for your practice check these out and try to solve at your own pace if  you find some difficulties then get back to me.

Q1. 78 - [5 + 3 of (25 - 2 × 10)]

Q2.  52 - 4 of (17 - 12) + 4 × 7
