Adding and Subtracting Integers

I can perform operations with integers and explain the rules for positive and negative signs.

• 1

  When adding integers with different signs, take the greater absolute value and subtract the lesser; the answer takes the sign of the greater absolute value.

• 2

  When subtracting integers, you must add the opposite of the second number to the first number.

• 3

  Adding a negative number decreases the value, while subtracting a negative number increases the value.
