2 + 3 x 7 = 23.
The first operation to be done is division,
since 25 divided by 5 is 5,
the value is equal to
The next operation to be done is multiplication,
Since 2 x 3 = 6,
Mathematics or the operations on numbers don't change,
what changes is when to perform the operation, that is the order.
When brackets are used, the operations inside the brackets ought to be performed first.
It may be observed that the operations in the innermost brackets are performed first.
Character is who you are when no one is looking.
