Question

Write the number with appropriate signs: Any five numbers less than 0.

Answer 1

Hint: Write five different numbers that are less than 0. Use the concept of number line to check if the numbers are less than 0 or not. Write a sign of each number.
* Any number lying on the left hand side of 0 on the number line is negative in sign. Similarly any number lying on the right hand side of 0 on the number line is positive in sign.
* A number line is a representation of numbers on a straight line that extends on both sides (right as well as left) with equal distance between consecutive numbers.

Complete step-by-step answer:
We draw a number line representing few numbers on the left hand side and few on the right hand side of 0.

Since we have to find five numbers less than 0; from the number line we can choose any five numbers that are on the left hand side of 0.
We take five numbers as -1, -2, -3, -4 and -5.
Since the sign of every number less than 0 is negative.

Five numbers that are less than 0 are -1, -2, -3, -4 and -5.

Note: Alternate method:
We use subtraction as a method.
We can find numbers less than 0 by subtracting numbers from 0.
\[0 - 19 = - 19\],\[0 - 1888 = - 1888\],\[0 - 7 = - 7\],\[0 - 4 = - 4\] and \[0 - 1 = - 1\]
\[\therefore \]Five numbers that are less than 0 are -19, -1888, -7, -4 and -1.
(All numbers that are less than 0 have negative signs, so we can choose any number from -1 to \[ - \infty \]. Similarly all numbers that are greater than 0 have positive signs.)
