Scienti c Functions

This calculator has a variety of functions. Press m0to select NORMAL mode and perform scientiﬁc calculations.

•For basic calculations, see page 11.

•When a listed ﬁnancial variable is displayed, you can enter the result of a scientiﬁc calculation into it by pressing Q immediately after completing the calculation.

•Scientiﬁc calculations can also be performed in STAT mode.

•The examples in this chapter are all performed under the SET UP menu’s default settings. Before starting calculation, press sto clear the display.

Constant Calculations

			Example		Key operation			Result
34		+ 57		=	s34	+57	=	9100

45		+ 57		=	45 =			10200
45				=				10200

	68 ⋅		25 =		68 x25 =			170000

68 ⋅ 40 =					40 =			272000

•In constant calculations, the addend becomes a constant. Subtraction and division behave the same way. For multiplica- tion, the multiplicand becomes a constant.

•In constant calculations, constants will be displayed as .

Chain Calculations

A calculation result (ANS memory) can be used in a subse- quent calculation. However, it cannot be recalled after entering multiple instructions.

Example	Key operation		Result

6 + 4 = ANS	s6	+4 =	1000
ANS + 5 =	+5	=	1500

8 ⋅ 2 = ANS	8 x2 =		1600
ANS2 =	.;=		25600

44 + 37 = ANS	44 +37 =		8100
ANS =	.}=		900
