25
ADDITION / SUBTRACTION of Integers STEPS : 1. 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 : 1. 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.

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. 1 st change double sign ++ means + Add the two integers

28
ADDITION / SUBTRACTION of Integers STEPS : 1. 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. 1 st change double sign + - means - Add 3 and 4 and place a negative sign in front

29
ADDITION / SUBTRACTION of Integers STEPS : 1. 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. 1 st 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 : 1. 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

ADDITION / SUBTRACTION of Integers STEPS : 1. 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 1 st change double sign - + means - Subtract; 8 – 4

32
ADDITION / SUBTRACTION of Integers STEPS : 1. 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 1 st change double sign - + means - The difference between 8 and 4 = 4. Since 8 is farther away from zero and negative, the answer is negative
