Brackets in formula in Excel

Sometimes you will need to use brackets, (also known as 'braces'), in formula.
This is to ensure that the calculations are performed in the order that you need.
The need for brackets occurs when you mix plus or minus with divide or multiply.
Mathematically speaking the * and / are more important than + and - .
The * and / operations will be calculated before + and - .
Example 1 : The wrong answer !
	10
	20
	2
	50	=C12+C13*C14
	You may expect that 10 + 20 would equal 30
	And then 30 * 2 would equal 60
	But because the * is calculated first Excel sees the
	calculation as 20 * 2 resulting in 40
	And then 10 + 40 resulting in 50
Example 2 : The correct answer.
	10
	20
	2
	60	=(C27+C28)*C29
	By placing brackets around (10+20) Excel performs this
	part of the calulation first, resulting in 30
	Then the 30 is multipled by 2 resulting in 60
