3. * FACTORS: Numbers that you multiply to have a product. Ex: Factors of 24 1X24= 24 2X12= 24 3X8 = 24 4X6 = 24 List: 1, 2, 3, 4, 6, 8, 12 and 24.

4. * MULTIPLES: The product of a given whole number and any other whole number. Ex: Multiples of 24: 24, 48, 72, 96, 120,...

5. * LEAST COMMON MULTIPLE OF 4 AND 5 * Mutiples of 4 : 4, 8, 12, 16, 20, 24, … * Mutiples of 5: 5, 10, 15, 20, 25, 30,… * LCM: 20

6. * PRIME NUMBERS: Numbers that only have 2 factors (1 and the number itself). Ex: 2 1X2 = 2 1,2 11 1X 11 = 11 1, 11 * COMPOSITE NUMBERS: Numbers that have more than 2 factors. Ex: 12 1X12= 12 2X6=12 3X4=12 1, 2, 3, 4, 6, 12

7. * ATTENTION! 1 and 0 are nor prime or composite! * NUMBER SQUARE: A number that has been multiplied by itself. Ex: 16 4X4= 16 25 5x5= 25

8. * EXPONENTS (EXPOSANTS): 5X5X5= 5 exponent 5 = 125

9. * 1. Commutative property: You can change the order of the factors. Ex: 50 X 4 = 4 X 50 2. Associative property: You can change the grouping of factors. Ex: (7 X 25) X 4 = 7 x (25 x 4)

10. * 3. Distributive property Ex: 4 X 28 = 4 X (20 + 8) = (4X20) + (4x8)= 112 * 4. Identical property Ex: 1 X 243 = 243 * 5. Zero property Ex: 0 x 243 = 0

11. * STEPS TO FOLLOW IN A DIVISION: * 1. Daddy-Divide (How many times the divisor goes into part of the dividend?) * 2. Mommy-Multiply * 3. Sister- Subtract * 4. Brother-Bring Down * 5. Daddy-Divide

12. * ORDER OF OPERATIONS: * 1. Parenthesis, brackets, braces (Go from the * inside to the outside) * 2. Exponents: 3X3X3 = 3 exponent 3 = 27 * 3. Divisions or multiplications in the order that they appear in the equation from left to right. * 4. Subtractions or additions in the order that they appear in the equation from left to right.
