Addition Basics: 2 positive numbers added together equal a positive =+4

2 negative numbers added together equal a negative = -7 ( -a + -b = -a +-b)

Addition of Integers To add a negative number and a positive, subtract the smaller number from the larger and attach the sign of the larger number to the resulting sum. Ex: )Take the smaller number and subtract it from larger number : 7-3=4 2)Next, Attach the sign of the larger number: 7 is positive so a positive 4

Subtraction of Integers Adding Opposites Approach Subtracting an integer is the same as adding its opposite!

Adding Opposites Approach 2 – (-8) add the opposite of =10 An opposite of a number is a number whose distance is the same distance from zero spaces/units

Subtraction of Integers In the case of a double negative: 2 negatives cancel each other out to make a positive. Ex: -3-(-4)= 1 Makes a positive
