Addition of Integers

Rule 1: Both integers are positive

• Add them normally.
• The result is positive.

Example: (+3) + (+2) = +5

Rule 2: Both integers are negative

• Add their magnitudes.
• The result is negative.

Example: (-12) + (-67) = -79

Rule 3: One positive, one negative

• Subtract the smaller number from the larger one (ignore signs).
• The result takes the sign of the number with the larger magnitude.

Example: (-38) + 72 = 34
Conversely, (-72) + 38 = -34

Representation of the Rabbit’s Hops on a Number Line Using Positive and Negative Signs:
1. For Positive signs

• At first the rabbit was at the number
• It hopped 5 units to the right.
• The number is currently at +6.

Calculation:
1 + 5 = (+1) + (+5) = +6
2. For Negative Signs

• Initially, the rabbit was positioned at number -2.
• It hopped 5 units to the right.
• It is now at the number +3. 
  

Calculation:
(-2) + (+5) = +3
