How will the difference of two numbers change if (-3) is added to the subtrahend

Step-by-step explanation:
Integers are the numbers made from the set of whole numbers and their opposites.
Example:
2 and -2
The difference is the answer for a subtraction problem.
Example:
A - B = C
C is the difference or answer for the subtraction problem.
The minuend is the number from which other number subtracted.
Example:
9 - 6 = 3
The minuend is the number 9.
The subtrahend is the number that is to be deducted from another number.
Example:
9 - 6 = 3
The subtrahend is the number 6.
The difference between two positive integers can be either positive, negative or zero.
When the first positive integer (or minuend) is larger than the second positive integer (or subtrahend) in a subtraction problem, the difference will be positive.
Example #1:
5 - 4 = 1
Note: A plus symbol is not necessary to represent a positive number. The positive number is assumed. Therefore, 3 is a positive number.
When the second positive integer (or subtrahend) is larger than the first positive integer (or minuend) in a subtraction problem, the difference will be negative.
Example #2:
3 - 7 = -4
When both integers have the same value, the difference is zero.
Example #3:
8 - 8 = 0
The difference between a positive and a negative integer can be positive or negative.
When you subtract a negative integer from a positive integer, the difference is always positive.

Example #3:

-7 - 3 = -10

Note: A plus symbol is not necessary to represent a positive number. The positive number is assumed. Therefore, 3 is a positive number.

The difference between two negative integers can be positive, negative or zero depending upon the values of the integers.

When you subtract two negative integers and the first integer (or minuend) is smaller than the second integer (or subtrahend), the difference is negative.

Example #1:

-8 - (-2) = -6
When you subtract two negative integers and the first integer (or minuend) is larger than the second integer (or subtrahend), the difference is positive.

Example #2:

-2 - (-8) = 6

Above is correct i went over it :)

The answers are 20,30,80,180,960,890,1230,4560. on the first row
