Distributive Property Explanation of Distributive Property Distributive Property is a property of numbers that ties t he operation of addition ( Subtract) and multiplication together. The Rules Of Distributive Property It says that for any numbers 9, 13, C, A x ( B + C) = A x B + A x C. For those used to multiplications without the multiplication sign The same property applies when there is subtraction instead of addition How It is Used The Distributive property is used when something in parentheses is multiplied by something, or, in reverse, when you need to take a common multiplier but of the parentheses Ex. X(2y-3) : 2 x y 3x 2

P o s i t i v e a n d N e g a t i v e I n t e g e r s Everyone knows how to add, subtract, multiply, and divide positive integers, but what about negative inters? If done correctly, negative integers can be a lot like positive integers. The main thing to know about negative numbers is that not all equations using negative numbers are actually negative, they can be positive too! Think of adding integers like hot and cold cubes, with negative integers being cold. When you add two or more cold cubes together, you get an even colder tempeture and vice versa with hot cubes, but adding hot cubes to cold cubes is a bit more complicated. As previously stated, negative numbers plus positive numbers are more complicated than positive plus positive. Using the hot and cold cube strategy can be helpful. When there are more hot cubes then cold cubes, the result will be positive, EXAMPLE: -10 + 20 = 10 This is similar to more cold cubes then hot EXAMPLE: 10 + (-20) = (-10) When using two negative integers, the sign stays the same. EXAMPLE: -10 + (-20) = (-30) Subtracting negative integers are just like adding, except when using two different integers. When a smaller number is subtracted from a bigger number, the result is negative. EXAMPLE: 5 10 = (-5) When a positive number is subtracted from a negative number, the answer I decided whether the positive or negative number is bigger. EXAMPLE: -20 10 = (-10) OR 20 (-10) When using more than two integers, the larger amount decides the answer. EXAMPLE: 10 (-20) 30 (-40) = 0 Multiplying integers are pretty easy: when there are an even number of negative numbers, the answer is positive. EXAMPLE: -10 x -10 = 20 When there is an odd number, the answer is negative. EXAMPLE: -10 x 10 x -10 = -200 Use the same strategety used for multiplying for dividing. EXAMPLE: -10 / -10 = 100 positive. EXAMPLE: -10 x -10 =20 When multiplying an odd number of negative numbers, the answer is always negative. EXAMPLE: -10 x (-10) x 10 = (- 200) EXAMPLE: 10 / (-10) / (-10) = (- 200 ) THE END!!!!!! !!!!!!! 3

Rule 2 When adding integers if opposite signs, take their absolute values, subtract smaller from larger, and give the result with the sign that has a larger value. 15+(-17)=-2 Subtracting Add the opposite! 4-7 4+(-7) -3 Adding Rule 1 When adding integers of the same sign, add their absolute value and give the same sign. Example: -15+(-15)= -30 BY: Ben 4

Adding And Subtracting Integers. BY: Abby Adding integers having the same sign. Rule #1 Add the numbers as if they were positive then add the sign of the numbers. Example -5+(-3) or 5+3 then add the sign Rule #2 Adding integers with different signs Take the difference of the two numbers as if they were positive then give the result the sign of the absolute value or the bigger number. Example -5+3 = 2 or 5-3 = 2. Subtracting Integers Rule#1 When we subtract Integers we would ADD THE OPOSITE!!! Then follow the steps of addition. Example 5-(-3) becomes 5+3 or -5-(-3) becomes -5+(-3)= -2 Adding integers having the same sign. Rule #1 Add the numbers as if they were positive then add the sign of the numbers. Example -5+(-3) or 5+3 then add the sign Rule #2 Adding integers with different signs Take the difference of the two numbers as if they were positive then give the result the sign of the absolute value or the bigger number. Example -5+3 = 2 or 5-3 = 2. Subtracting Integers Rule#1 When we subtract Integers we would ADD THE OPOSITE!!! Then follow the steps of addition. Example 5-(-3) becomes 5+3 or -5-(-3) becomes -5+(-3)= -2 5

Adding and Subtracting Integers ADDITION Rule #1- When adding integers having the same sign: Add the Numbers as if they are positive and then add the sign of the numbers. Example: -4+(-8)=? -> 4+8=12 then add the negative -4+(-8)= -12 Rule #2- When adding integers having different signs: Take the difference of the numbers as if they are positive, then give the result of the number with the greatest absolute value. Example: 8+(-17)=? -> 17-8=9 -> 8+(-17)=-9 Subtraction Rule- Add the opposite! (this rule applies to all subtraction) then, follow the rules to addition. Example: 3-(-12)=? -> 3+12=15 & -3-12=? -> -3+(-12)=9 6

Examples: -6 + -2 = -8 -10 + -10 =-20 -2 + -5 = -7 Rule: If you add two negative Integers you have a Negative Integer. ADD SUBTRACT MULTIPLY DIVIDE MATH PROJECT AHMER Rule: When you add a positive integer with a negative integer you get either a Negative or positive because it depends on which number is bigger. Examples: -20+10 = -10 45+(-12) =33

By: Brian When multiplying an even number of negative integers the product will always be positive. Example: -8(-5)=40 Rule#2 When multiplying and odd number of integers the product will always be negative. Example:-9(5)=45

Adding and Subtracting Integers Hailey Adding Integers With The Same Sign Rule: Add numbers as if they were positive, then add the sign of the numbers Ex. (-3)+(-8) 3+8=11 (-11) Adding Two Integers Having Different Signs Rule: Take the difference of the two numbers as if they were positive then give the result the sign of the number with the greatest absolute value (dominant) Ex. -5+3 5-3=2 (-2) Subtracting Integers Rule: When we subtract integers, we add the opposite then use the rules for addition Ex. 7-(-6) 7+6=13 13

Distributive property This is the distributive property. 1.You take the first number/variable and multiply it by the second number/ variable Example: 3(4+a) 3x4 3(4+a) 3xa 2. Then when you add or subtract depending on the sign in the problem. Do the same to the second number variable. Example: 3x4 + 3xa 3.Then finish the problem. 3x4 12 + 3xa 3a = 12 + 3a 3(4+a) 3x4 + 3xa By: Isabelle

Multiplying and Dividing Integers By: Tatiana 1.When multiplying or dividing two integers with the same sign the answer to the equation is always a positive number. 2.When multiplying or dividing two integers with different signs the answer to the equation is always a negative number. 3.When multiplying or dividing more than two numbers that include a negative number count how many negative numbers there are. If there is an even amount of negative numbers then the answer is a positive number. If there is an odd amount of negative numbers than the answer will be a negative number. Examples:1.3 3 = 9 -3 (-3)= 9 4 4= 1 -4 (-4)= 1 2. 2 (-5)= -10 6 (-3)= -2 3. -2(-2)-2)(-2)= 16 3(-9) (-8)= 216 3(-2) (-4) (-2)= -48 -2(-2)(-2)= -8

1) When adding integers of the same sign, we add their absolute values, and give the result the same sign. 2) 2 + 5 = 7 (-7) + (-2) = -(7 + 2) = -9 (-80) + (-34) = -(80 + 34) = -114 3) When adding integers of the opposite signs, we take their absolute values, subtract the smaller from the larger, and give the result the sign of the integer with the larger absolute value. 4) 8 + (-3) = ? The absolute values of 8 and -3 are 8 and 3. Subtracting the smaller from the larger gives 8 - 3 = 5, and since the larger absolute value was 8, we give the result the same sign as 8, so 8 + (-3) = 5. 5) By Will Malone Adding Integers

Combine like terms. Using the properties of real numbers and order of operations you should combine any like terms. Isolate the terms that contain the variable you wish to solve for. Use the Properties of Addition, and/or Multiplication and their inverse operations to isolate the terms containing the variable you wish to solve for. Isolate the variable you wish to solve for. Use the Properties of Addition and Subtraction, and/or Multiplication and Division to isolate the variable you wish to solve for on one side of the equation. Substitute your answer into the original equation and check that it works. Every answer should be checked to be sure it is correct. After substituting the answer into the original equation, be sure the equality holds true.
