AND ANSWERS 2025
Purpose of the module - correct answer- To enable a student to
become conversant with a variety of basic quantitative
techniques.
Order of operations - correct answer- A set of rules that defines
the correct sequence to evaluate a mathematical expression.
Brackets - correct answer- Symbols used in mathematics to
group parts of an expression.
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.
Multiplication of fractions - correct answer- The process of
multiplying the numerators and denominators of two fractions.
Division of fractions - correct answer- The process of
multiplying by the reciprocal of the divisor fraction.

Subtracting fractions - correct answer- The process of finding a
common denominator to find the difference between two
fractions.
Decimals - correct answer- Numbers that represent fractions
with a denominator of ten or a power of ten.
Positive powers - correct answer- Exponents that indicate how
many times a number is multiplied by itself.
Negative powers - correct answer- Exponents that indicate the
reciprocal of a number raised to a positive exponent.
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.
Proportion - correct answer- An equation that states two ratios
are equal.

numbers as points at equal intervals.
Positive and negative numbers - correct answer- Numbers that
are greater than zero (positive) or less than zero (negative).
Summation - correct answer- The process of adding a
sequence of numbers.
