Question

Find the value:|4-9|​

Answer 1

Answer:

modulus of (4 -9) = 5

Step-by-step explanation:

No matter how far a number is from its origin, or point 0 (zero), which is a part of real straight line, its modulus or absolute value will always be positive (or zero). Two vertical bars make up the modulus sign, which is used to represent the quantity.

the difference between two numbers within a modulus is given by :

$|a + b|$

or

$|a - b|$

but the answer is always in positive due to modulus.

here given,

$|4 - 9 |$

4 - 9 = -5

but due to modulus, the answer -5 becomes positive 5

thus modulus of (4 -9) =

$|4 - 9| = | - 5|$

$= 5$

thus the answer is 5 .
