1

Problem

Subtraction of integers:
(+2) - (+3) - (+5)

2

Step

The three integers are

\$ 2, 3, 5 \$

3

Step

Subtraction problem turns into an addition problem

\$ ((+ 2) + (- 3)) + (- 5) \$

4

Formula

If we follow the addition rule of positive and negative integers:

\$ (+) + (-) = "use the sign of larger absolute value number" \$

5

Step

Let us add both the positive and negative integers

\$ (2 + (- 3)) + (- 5) \$

6

Step

After adding the both positive and negative integers

\$( 2 - 3 ) + (-5) \$

7

Step

Simplify the both positive and negative integers

\$(- 1) + (- 5) \$

8

Step

Here we apply the rule of addition of negative integers

\$ (-) + (-) = (-) \$

9

Step

Let us add both the negative integers

\$ - 1 + (- 5) \$

10

Step

Simplify the negative integers

\$- 1 - 5 \$

11

Step

After adding

\$ - 6 \$

12

Solution

Therefore, the subtraction of integers is \$-6 \$.

Choices

14

Choice-A

When adding (+2), (-3), and (-5), the result is -6, making this option incorrect as it suggests -4

Wrong -4

15

Choice-B

This option’s claim of -2 contradicts the actual sum of (+2), (-3), and (-5), which is -6.

Wrong -2

16

Choice-C

This option is incorrect because when you add (+2), (-3), and (-5), you get -6, not -1.

Wrong -1

17

Choice-D

This option suggests -4, but the correct result of adding (+2), (-3), and (-5) is -6.

Correct -6
