Constant calculations

Example		Key operations	Result
34+57=	34+57e		91.
45+57=	45	e	102.
68⋅25=	68k25e		1700.
68⋅40=		40e	2720.

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

•In constant calculations, constants will be displayed as ∆.
