Variables E, I, N, O, Q, S are not allowed.Please enter variables only, constants like 0,1 are not allowed.Expressions inside brackets () are always evaluated first, overriding the precedence order. Boolean operations follows a precedence order of NOT AND OR.Do not omit the * operator for an AND operation. Use ~ * + to represent NOT AND OR respectively.Parentheses ( ) and brackets may be used to group terms as in a standard expression. Exponents may not be placed on numbers, brackets, or parentheses. Note: exponents must be positive integers, no negatives, decimals, or variables. ExponentsĮxponents are supported on variables using the ^ (caret) symbol. VariablesĪny lowercase letter may be used as a variable. Use the following rules to enter expressions into the calculator. When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms.
