D125 MATHEMATICS FOR ELEMENTARY
EDUCATORS I TEST PAPER 2026
QUESTIONS AND ANSWERS 100% CORRECT
⩥ Recurring Decimals. Answer: A decimal with a digit or string of digits
that repeats forever
⩥ Irrational Numbers. Answer: Numbers that cannot be represented as a
fraction of two integers. Decimals do not terminate or repeat.
⩥ Square Roots. Answer: For a given number, this is the number that
produces the given number when multiplied by itself
⩥ Perfect Square. Answer: The product of any integer with itself yields a
perfect square. So, a number is a perfect square if it can be written as the
square of an integer. For example, 9 is a perfect square because 3 * 3 = 9
⩥ Real Numbers. Answer: Any number on the number line. Real
numbers include whole numbers, integers, rational numbers, and
irrational numbers
⩥ Divisible. Answer: The quality of producing a quotient that is an
integer
, ⩥ Factors. Answer: An integer that evenly divides another integer
⩥ Prime Number. Answer: An integer greater than 1 that has only two
positive factors: one and itself (2, 3, and 5 for example)
⩥ Composite Number. Answer: An integer that has factors other than
itself and 1
⩥ Factorization. Answer: The process of finding the prime factors of a
composite number
⩥ Product. Answer: The result of multiplying
⩥ Factor Pair. Answer: Pair of factors that when multiplied together
produce the original number
⩥ Square Number. Answer: An integer that is the product of an integer
multiplied by itself
⩥ Fundamental Theorem of Arithmetic. Answer: Every integer greater
than 1 is either prime, or is the product of a unique set of prime numbers
⩥ Prime Factorization. Answer: Determining the set of prime numbers
whose product is the original integer
