12-7*6+19-14=11

Question

please tell me the method to put the parentheses at the right places

 

Answer 1

PEMDAS has M before A or S, or BODMAS, still M first, A,S next

so Multiply before Add or Subtract

that's the arithmetic order of operations

12-(7*6) +19 -14 = 11

12(-42 +19)-14 = 11

12-23-14 = 11

-11-14 = 11

-25 = 11 isn't true, unless you put in parentheses differently

(12-7)*6+19-14, Left to Right is popular, especially for English teachers

= 5*6 +19-14

= 30+19-14

=30+5 =35 Nope that doesn't =11 either

may not be a way to get left side to = 11, no matter how or where you put in parentheses

(12-7)*(6+19-14) = 5*11=55 Nope

Answer 2

You can add parentheses based on the operation with highest order.

You can use the BODMAS rule to remember the order

It means

B-Bracket

O-of

D-Division

M-Multiplication

A-Addition

S-Subtraction

So now if we see your question

It can be

4-(3*7)-(12/6)+2 Division and Multiplication are almost of same degree but Division has a bit higher degree than Multiplication

(4-(3*7))-(12/6)+2

((4-(3*7))-(12/6))+2

(((4-(3*7))-(12/6))+2)

Answer 3

You want to think about order of operations - PEMDAS.  Since you are working toward a result, I would just do guess and check. It's a tricky one! You will need nested sets...paratheses within paratheses.

Answer 4

Add the parentheses based on highest order of operation, then left to right.

example:

• 4-3*7-12/6+2 = x
• 4-(3*7)-(12/6)+2 = x  Multiplication and division are higher order than add and subtract, but                                      the same as each other so they are left to right.
• (((4-(3*7))-(12/6))+2) Addition and subtraction are the same order of precedence so they are                                       just done left to right.

Hope this example helps,
