On Monday, Anand purchased 8 chocolates each for ₹10. On Tuesday, he purchased 3 chocolates each for ₹10 again. How much he spent in both the days for chocolates.
 
This can be done in two ways:
  1. Monday spent + Tuesday spent = 8×10+3×10=80+30=110.
  2. Total number of chocolates he purchased in both the days × Amount spent for each chocolate = 8+3×10=11×10=110.
There are some confusions in the calculation. Which operation has to be done first?
 
Whether we have to multiply 3 by 10 first and then add with 8 or we have to add 8 and 3 and multiply by 10?
 
To get a clear view in order of operation, we have to insert brackets.
First, reduce the number which is present inside the bracket ( ) into a single number and then do the operation outside.
