Question

Add using number line -6 +3 -7-4 -8-(-4) 7+(-5) 7-(-8) -9+(-4)-(-8)​

Answer 1

To solve : $-6 + 3 - 7 - 4 -8 -( - 4 ) 7 + ( -5 ) 7- ( -8 )-9+ (-4) - (-8 )$

Solution:-

To solve the above equation we will follow BODMAS rule.

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

where, B = brackets

            O = order of powers or rule

            D =  Division  

            M =  multiplication  

             A = addition

             S = subtraction

As we know , $( - ) \times ( - ) = + \ and\ ( + ) \times ( -) = \ -$   remembering these solve and According to above rule we will solve :$-6 + 3 - 7 - 4 -8 -( - 4 ) 7 + ( -5 ) 7- ( -8 )-9+ (-4) - (-8 )$

now , $- 6 + 3 - 7 - 4 - 8 + 28 - 35 + 8 - 9 -4 + 8$

on performing simple addition and subtraction we get ,

$- 6 + 3 - 7 - 4 - 8 + 28 - 35 + 8 - 9 -4 + 8 = -26$

Hence , $-26$ is the required answer.

Answer 2

Given,

$-6+3-7-4-8-(-4)7+(-5)7-(-8)-9+(-4)-(-8)$

Here, we have to solve this given expression by using BODMAS rule

B-Border

O-Of

D-Division

M-Multiplication

A-Addition

S-Subtraction

We know that,

$-\times-=+\\-\times+=-\\+\times+=+$

We have to apply this rules to simplify the given expression,

$-6+3-7-4-8-(-4)7+(-5)7-(-8)-9+(-4)-(-8)$

$=-6+3-7-4-8+28-35+8-9-4+8$

$=-6+3-7-4-8+28-35+8-9-4+8\\=47-73$

$=-26$

Therefore, the answer is $-26$.
