Brackets in formula

	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
