E-72Sequence Operation Type Description7 Multiplication, DivisionOmitted Multiplication Sign×, ÷Multiplication sign can be omitted immediatelybefore π, e, variables, scientific constants (2π, 5A,πA, 3mp, 2i, etc.), and parenthetical functions(2'(3), Asin(30), etc.)8 Addition, Subtraction +, −9 Relational Operators =, ≠, >, <, >, <10 Logical Product and11 Logical Sum, Exclusive LogicalSum, Exclusive NegativeLogical Sumor, xor, xnorNote• If a calculation contains a negative value, you may need to enclose the negative value inparentheses. If you want to square the value –2, for example, you need to input: (–2) 2. This isbecause x2 is a function preceded by a value (Priority 2, above), whose priority is greater than thenegative sign, which is a prefix symbol (Priority 4).-cxw –2 2 = –4(-c)xw (–2) 2 = 4• Multiplication and division, and multiplication where the sign is omitted are the same priority(Priority 7), so these operations are performed from left to right when both types are mixed in thesame calculation. Enclosing an operation in parentheses causes it to be performed first, so theuse of parentheses can result in different calculation results.b$c.(i)w 1 { 2i = 12 ib$(c.(i))w 1 { (2i) = – 12 ik Stack LimitationsThis calculator uses memory areas called “stacks” for temporary storage of lower calculation prioritysequence values, commands, and functions. The “numeric stack” has 10 levels and the “commandstack” has 24 levels as shown in the illustration below.A Stack ERROR occurs when the calculation you are performing causes the capacity of a stack tobe exceeded.1 2 3 4 51 2 3 4 5 6 71 2 3 4 51 2 3 4 5 6 7Numeric Stack Command Stack12345234541234567Numeric Stack Command Stack12345234541234567
