INTEGER+RULES

__Integer Rules __

__Adding Integers __

•Same Signs: Add the numbers and keep the same sign. Examples: -7 + -3 = -10 16 + 12 = 28 • Different Signs: Subtract the numbers and use the sign that has more. Examples: -12 + 7 = -5 15 + -8 = 7

__Subtracting Integers __

•Subtracting = Adding the opposite. Examples:

-20 − -10 = -20 +  10 = -10 -20 − 10 = -20 +- 10 = -30 <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 19px;">20 − -10 = 20 <span style="color: red; font-family: 'Arial','sans-serif'; font-size: 19px;">+ <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 19px;"> 10 = 30 <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 19px;">20 − 10 = 20 <span style="color: red; font-family: 'Arial','sans-serif'; font-size: 19px;">+- <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 19px;">10 = 10

<span style="color: black; font-family: 'Arial','sans-serif'; font-size: 19px;">•Same signs = Positive answer. Examples:

<span style="color: black; font-family: 'Arial','sans-serif'; font-size: 19px;">-9 • -9 = 81 -72 ÷ -9 = 8 <span style="color: black; display: block; font-family: 'arial','sans-serif'; font-size: 19px; text-align: center;">9 • 9 = 81 <span style="color: black; display: block; font-family: 'arial','sans-serif'; font-size: 19px; text-align: center;">72 ÷ 9 = 8

<span style="color: black; font-family: 'Arial','sans-serif'; font-size: 19px;">•Different Signs = Negative answer. Examples:

<span style="color: black; font-family: 'Arial','sans-serif'; font-size: 19px;">-6 • 8 = -48 -36 ÷ 4 = -9 <span style="color: black; display: block; font-family: 'arial','sans-serif'; font-size: 19px; text-align: center;">6 •-8 = -48 <span style="color: black; display: block; font-family: 'arial','sans-serif'; font-size: 19px; text-align: center;">36 ÷ -4 = -9
