Question

12 - 3[ 5 + 3 {(7 - 9) - 2}]
​

Answer 1

Answer:

33

Step-by-step explanation:

12-3[ 5+3 {(-2)-2}]

= 12-3[5+3 {-4}

= 12-3[5 -12]

= 12-3[-7]

= 12+21

= 33

I don't know if you meant to put addition symbol outside the brackets, but this  answer is by multiplying, as when there is no symbol in front of brackets, it is multiplied.

A - Addition

S - Subtraction

All of them need to be followed in a specific and same order to get the correct answer.

Following the above mentioned information ; we will solve the given problem :

$\longrightarrow{\sf{12 - 3 [ 5 + 3 {(7 - 9) - 2}] }}$

$\longrightarrow{\sf{12 - 3 [5 + 3 {-2 - 2}] }}$

$\longrightarrow{\sf{12 - 3 [5 + 3 \times (-4)]}}$

$\longrightarrow{\sf{12 - 3 [5 + (-12)]}}$

$\longrightarrow{\sf{12 - 3 [5 - 12]}}$

$\longrightarrow{\sf{12 - 3 \times (-7)}}$

$\longrightarrow{\sf{12 + 21 }}$

$\large{\boxed{\implies{\sf{33}}}}$
