Question

Arranging the numerical figures in an ascending or a descending order is called an _______.

Answer 1

Hint: We recall the definition of order, numerical figures, descending order or ascending order. We recall that the collection of arranged numerical figures is called an array and fill the word ‘array’ in the given blank.

Complete step-by-step answer:
We know that when we say we arrange figures in ‘order’ it means we are writing the figures one after one separated by a comma such that there is the same relation between two consecutive figures each figure each called a ‘term’. For example the natural numbers are in order 1, 2, 3... , where the relation between any two consecutive natural numbers $a,b$ is given by $a$ less than $b$.
A numerical figure is any real number. We know when we arrange real numbers in ascending order it means arranging them in from the smallest number to largest number, for example if we want to arrange the numbers $\pi ,1,{\displaystyle \frac{-3}{2}},5,2.75$ in ascending order we can have ${\displaystyle \frac{-3}{2}},1,2.75,\pi ,5$.
We know when we arrange real numbers in descending order it means arranging them in from the smallest number to largest number, for example if we want to arrange the numbers $\pi ,1,{\displaystyle \frac{-3}{2}},5,2.75$ in descending order we can have $5,\pi ,2.75,1,{\displaystyle \frac{-3}{2}}$.
The collection of arranged numerical figures is called an array. An array also may be rectangular in which case it is called matrix. So we need to fill the word ‘array’ in the blank.

Note: We note the action of the numerical figures in an ascending or a descending order is called ‘sorting’ but the result of arranging is called array. The array is a different collection from the set where belongingness to the collection is more important not the order of elements.
