HP 35s Scientific Order, Example, Meaning, Operation, Equations, Entering and Evaluating Equations

Order	Operation	Example
1	Parentheses	
2	Functions	
3	Power ( )	
4	Unary Minus ()	
5	Multiply and Divide	, 
6	Add and Subtract	, 
7	Equality	

So, for example, all operations inside parentheses are performed before operations outside the parentheses.

Examples:

Equations	Meaning
	a ⋅ (b3) = c
	(a ⋅ b)3 = c
	a + (b/c) = 12
	(a + b) / c = 12
	[%CHG ((t + 12), (a – 6)) ]2
