Variables - correct answer- Symbols that represent unknown
values in mathematical expressions.
Commutative laws - correct answer- Laws stating that the order
of addition or multiplication does not change the result.
Associate laws - correct answer- Laws that state how numbers
can be grouped in addition or multiplication without changing
the result.
Distributive law - correct answer- A property that allows
multiplication to be distributed over addition or subtraction.
Types of fractions - correct answer- Different classifications of
fractions, such as proper, improper, and mixed fractions.
Reducing fractions - correct answer- The process of simplifying
a fraction to its lowest terms.

Square root - correct answer- A value that, when multiplied by
itself, gives the original number.
Cube and higher order roots - correct answer- Values that,
when raised to the third or higher power, yield the original
number.
Fractional exponents - correct answer- Exponents that are
fractions, representing roots of numbers.
Ratios - correct answer- A comparison of two quantities
expressed as a fraction.
