Question

33-9+40-(30+15) = ??

Replace ( ?? ) with the correct answer and explaination​

Answer 1

Given:

A mathematical expression 33 - 9 + 40 - (30+15)

To Find:

The value of the expression.

Solution:

The given question can be solved by using the BODMAS rule.

• The BODMAS is the short form of Brackets, Of, Division, Multiplication, Addition, Subtraction.
• The BODMAS rule is the correct order for calculating any mathematical operations, The order followed is Bracket > Of > Division > Multiplication > Addition > Subtraction.

The given expression is 33 - 9 + 40 - (30+15),

1. Bracket is given the first preference, so it is solved first.

=> 33 - 9 + 40 - (45),

=> 33 - 9 + 40 - 45,

2. The next priority is given to addition than subtraction.

=> 33 - 9 + 40 - 45,

=> 33 + 31 -45,

=> 64 - 45,

3. Now the expression is only left with subtraction,

=> 64 - 45 ,

=> 19.

Therefore the value of the given expression is 19.

Answer 2

Answer:

=> 19

Step-by-step explanation:

Given that:-

$33-9+40-(30+15)$

To find:- The value of the expression  

For simplifying the expression, we have to use the BODMAS concept.

It is the rule used to remember the order of operations that is followed while solving expressions in mathematics.  

        where,    

        B= bracket  

        O= order of power or rules  

        D= division  

        M= multiplication    

        A= addition    

        S= subtraction  

As we have,

=> $33-9+40-(30+15)$

Simplifying it further, we get

=> $33-9+40-(45)$

Subtracting the terms, we get

=> $24+ ( -5)$

=> 24 - 5

=> 19

Hence, the required solution is 19.
