General Information

Basic Calculations

Entering numbers and arithmetic operations

•Use the number keys 0to 9, decimal point key ., and sign change key ,to enter numbers into the calcula- tor. To clear the display or entry, press s.

•Use the Skey to enter a value in scientiﬁc notation.

•Use the arithmetic keys +-x8to perform the standard arithmetic calculations of addition, subtraction, multi- plication, and division. Press =to perform each calculation.

•Use the (and )keys to place parentheses around inner parts of expressions. The closing parenthesis )just before =or hmay be omitted.

•When you enter a series of operations in one sequence, the calculator performs the calculation according to the priority levels in calculation on page 81.

			Example			Key operation			Result
	45		+ 285 ÷ 3 =		s45 +285 83 =				14000

		18	+ 6	=	(18	+	6 )8		343
					(15	-	8 =
	15		– 8

	42		⋅ (–5) + 120 =		42 x,		5 +120 =		-9000

					*1 (5 ,)		*1

		(5 ⋅ 103) ÷ (4 ⋅ 10–3) =			5 S3 84 S				125000000
