25
**ADDITION / SUBTRACTION of Integers**

STEPS : change any “double” signs Double signs such as or need to be changed to single signs… + + changes to + - - changes to + + - changes to - - + changes to -

26
**ADDITION / SUBTRACTION of Integers**

STEPS : change any “double” signs 2a. The sum of two positive integers is positive 2b. The sum of two negative integers is negative 2c. The sum of a positive and negative integer is the difference between the two numbers, then your answer takes on the sign of the integer the farthest away from zero.

27
**ADDITION / SUBTRACTION of Integers**

STEPS : change any “double” signs 2a. The sum of two positive integers is positive 2b. The sum of two negative integers is negative 2c. The sum of a positive and negative integer is the difference between the two numbers, then your answer takes on the sign of the integer the farthest away from zero. 1st change double sign ++ means + Add the two integers

28
**ADDITION / SUBTRACTION of Integers**

STEPS : change any “double” signs 2a. The sum of two positive integers is positive 2b. The sum of two negative integers is negative 2c. The sum of a positive and negative integer is the difference between the two numbers, then your answer takes on the sign of the integer the farthest away from zero. 1st change double sign means - Add 3 and 4 and place a negative sign in front

29
**ADDITION / SUBTRACTION of Integers**

STEPS : change any “double” signs 2a. The sum of two positive integers is positive 2b. The sum of two negative integers is negative 2c. The sum of a positive and negative integer is the difference between the two numbers, then your answer takes on the sign of the integer the farthest away from zero. 1st change double sign + + means + Subtract; 4 – 3 =1…since +4 is farther from zero than - 3, the answer is +

30
**ADDITION / SUBTRACTION of Integers**

STEPS : change any “double” signs 3a. A larger integer minus a smaller integer is positive - just subtract normally 3b. A smaller integer minus a larger integer is negative - find the difference, then the integer farther from zero gives + or - 3c. A negative integer minus a negative integer is negative - exactly like 2b in the addition set

31
**ADDITION / SUBTRACTION of Integers**

STEPS : change any “double” signs 3a. A larger integer minus a smaller integer is positive - just subtract normally 3b. A smaller integer minus a larger integer is negative - find the difference, then the integer farther from zero gives + or - 3c. A negative integer minus a negative integer is negative - exactly like 2b in the addition set 1st change double sign - + means - Subtract; 8 – 4

32
**ADDITION / SUBTRACTION of Integers**

STEPS : change any “double” signs 3a. A larger integer minus a smaller integer is positive - just subtract normally 3b. A smaller integer minus a larger integer is negative - find the difference, then the integer farther from zero gives + or - 3c. A negative integer minus a negative integer is negative - exactly like 2b in the addition set 1st change double sign - + means - The difference between 8 and 4 = 4. Since 8 is farther away from zero and negative, the answer is negative

A smaller integer minus a larger integer is negative - find the difference, then the integer farther from zero gives + or - 3c. A negative integer minus a negative integer is negative - exactly like 2b in the addition set 1st change double sign - + means - Add 8 and 4 , place a negative sign in front
