root Any number that is multiplied by itself a specific number of times
to equal another number. For example, in 3 × 3 ×3, the root is 3; in
4 ×4, the root is 4; in 5^4 , the root is 5, and so on.
roster method of specification (list method)The method in which the
elements or MEMBERSof a SETare listed. For example, A= {2, 4, 6, 8}.
An alternative method of listing elements of a set is the DESCRIPTION
METHOD OF SPECIFICATION.

rounding down functionThe process of lowering a number to the next
greatest number. For example, when rounding down the DECIMAL
4.312, the next greatest value is 4.31, and when rounding this
decimal down to a WHOLE NUMBER, that next greatest value is 4.
When rounding down the whole number 2,341 to the nearest
hundred, that next greatest value is 2,300. The guide used to
determine if a number should be rounded down or rounded up is
that any number below 5 is rounded down, and any number greater
than or equal to 5 is rounded up.
rounding up functionThe process of raising a number to the next greatest
number. For example, when rounding up the DECIMAL4.759, the next
greatest value is 4.76, and when rounding this decimal up to a WHOLE
NUMBER, that next greatest value is 5. When rounding up the whole
