What are the priorities of operations ?
When doing a calculation with addition, subtraction, division, multiplication, powers or mixed roots.
You must use the rule of priorities of operations to determine the order in which each operation must be performed.
We perform the operations in the following order:
In 1: The operations noted between the brackets
In 2: Powers, roots
In 3: Multiplication, division (from left to right)
In 4 : Additions, subtractions (from left to right)
