4. a number that can be expressed as the quotient or fraction ⁠⁠ of two integers
6. a rule or statement expressed using symbols that represents a relationship between variables or quantities
9. a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
11. a whole number that can be positive, negative, or zero, but it cannot have a fractional or decimal part.
