Question

Simplify: (– 3 + 4 – 9) – (– 7 – 10 + 9)​

Answer 1

Answer:

0

Step-by-step explanation:

At first solve bracket.

Apply the rules of BODMAS

So let's solve 1st bracket

(-3-9) = -12

-12+4 = -8

Now 2nd bracket

(-7-10) = -17

-17+9 = -8

(-8)-(-8) can be written as

-8+8

thus the ans is 0
