If a result is displayed in scientific
notation, you can press [ F <--> E ]
to convert the number to floating
point and vice- versa.
CONSTANT AND REPEAT
When performing calculations, the
last function and number entered are
retained as a constant.
Examples:
To calculate 7 + 5 + 5 + 5 = 22
Press 7 [ + ] 5 [ = ] [ = ] 22
In this case [ + ] and 5 are the con-
stants.
To calculate 2 + 3 = 5 and 4 + 3 = 7
Press 2 [ + ] 3 [ = ] 5 5
4 [ = ] 7
In this case [ + ] and 3 are the con-
stants.
When calculating powers
5 2 = 25 and 4 2 = 16
Press 5 [ yx] 2 [ = ] 25
4 [ = ] 16
In this case [ yx ] 2 is the constant.
