Question

Find the predecessor of each of the following integers.
 0 1 – 1 – 125 1000

Answer 1

Hint: To find the predecessor of the integer, subtract 1 from the given integer. So, first of all write the given integer and then subtract 1 from it to get the predecessor of the given integer. So, use this concept to reach the solution of the given problem.

Complete step-by-step solution -

 0
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
$$\Rightarrow 0-1=-1$$
So, the predecessor of 0 is – 1.
 1
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
$$\Rightarrow 1-1=0$$
So, the predecessor of 1 is 0.
  – 1
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
$$\Rightarrow -1-1=-2$$
So, the predecessor of – 1 is – 2.
 – 125
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
$$\Rightarrow -125-1=-126$$
So, the predecessor of – 125 is – 126.
 1000
We know that to find the predecessor of any integer, we need to subtract 1 from the given integer.
$$\Rightarrow 1000-1=999$$
So, the predecessor of 1000 is 999.

Note: Predecessor is also called as before numbers. Sometimes they ask to find the successor of the given integer. Then we simply need to add 1 to find the successor which is also called as after numbers of the given integer.
