Note: -Operators (, ), +, -, x, ÷, and ^ can combine into a long equation string. e.g. 17+2x3^2-4x5÷6.0+(7-8)x9÷5.0+6x7-5 -Computation follows operator precedence, e.g. 1+2x3-2^3+1 = 0.0 2x(3+4)÷3.0+5 = 9.666666666666668 -Operators !, % and 1/x can only be used in a single operation or first operator in mixed operation, e.g. 5!, 6%, but not 2 + 5!, not 20 + 5% -can use as first operator, e.g. 5! + 2, or 5% + 20 -Mod operator can not be mixed with other operators. -Mod usage: to compute 34 mod 5, e.g. tap 3 4, tap Mod, tap 5, tap =, result: 34 Mod 5 = 4.
