Question

Subtract the number which is successor of -27 from the number which is predecessor of -39

Answer 1

succesor of -27 is -26
predecessor of -39 is -40
-40-(-26)
-40+26
-14

Answer 2

Given : The number which is successor of -27 and the number which is predecessor of -39

To find : Their subtraction.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate their subtraction)

Here,

• Minuend = Predecessor of -39 = -39 - 1 = -40

[Predecessor of any number = That number - 1]

• Subtrahend = Successor of -27 = -27 + 1 = -26

[Successor of any number = That number + 1]

So, the subtraction will be :

= Minuend - Subtrahend

= -40 - (-26)

= -40 + 26

= -14

(This will be considered as the final result of the given mathematical problem.)

Hence, the answer is -14
