Answer:

Step-by-step explanation:

Given that:-

$21-12\div4-3\times(-7)$

To find:- The value of the expression

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

B - Brackets

O - order

 D - division  

M - multiplication  

A - addition  

S - subtraction

As we have,

=> 18 + 21  

=> 39

Hence, the required solution is 39.
