Answer 2

Answer:

heyyyy

before number of any number is known as predecessor and after number of any number is known as successor . For example : - 1 is the predecessor of 2 and 2 is the successor of 1.

here notable point is that " difference of predecessor number of a number from that number = 1. for example :- 8 is predecessor of 9 , then 9 - 8 = 1

And difference of a number from predecessor of that number = -1. for example:- 9 is predecessor of 10 then, 9 - 10 = -1

Now, according to question,

a is the predecessor of b , means a is before number of b

e.g., b = a + 1

Hence, (a - b) = (a - a - 1) = -1

And (b - a) = a + 1 - a = 1

i hope this makes you understand!

also please mark brainliest! that would make me every happy! :D
