Answer 1

Hey mate,
In this equation we follow the formula of BODMAS.
So first you will divide then multiply then add and then subtract but you will start solving it in brackets 1.( ) 2.{ } 3.[ ] and 4. The number outside all the brackets.
By this you will get answer 0.8.
If you need explanation then do let me know.
