Question

whats 21-4/1002-730+83920/839

Answer 1

The answer will be - 1.67 x $10^{-6$

Mathematical operations

The problem can be solved by using the rule of BODMAS.

21-4/1002-730+83920/839

First, the operation is divided into 3 parts

1. 21-4
2. 1002-730+83920
3. 839

For the first part:

    21 - 4 = 17

For the second part:

1002-730+83920

According to BODMAS, addition operations come before subtractions.

So, the operation becomes (1002)-(730+83920)

  = (1002) - (84650)  

     = -83648

The entire operation becomes 17/-83648/839

      17/-83648 x 1/839 = -17/70180672

                                  = - 1.67 x $10^{-6$
