4. Departamento Matemáticas Sección Bilingüe

5. Addition The process of finding the total number of items when two or more groups of items are joined; the opposite operation of subtraction Example: 3 + 2 = 5 Departamento Matemáticas Sección Bilingüe

6. Addend (sumando) A number that is added to another in an addition problem Example: 2 + 3 = 5 The addends are 2 and 3. Departamento Matemáticas Sección Bilingüe

7. Sum The answer to an addition problem Example: 12 + 7 = 19 The sum is 19. Departamento Matemáticas Sección Bilingüe

8. Departamento Matemáticas Sección Bilingüe Difference The answer in a subtraction problem Example: 8 - 5 = 3 3 is the difference.

9. Multiplication The process of finding the total number of items in equal- sized groups, or of finding the total number of items in a given number of groups when each group contains the same number of items It is the opposite operation of division. Example: 3 x 4 = 12 Departamento Matemáticas Sección Bilingüe

10. 4 4 x 7 = 28 x 7 28 Examples: The factors are 4 and 7. Factor A number that is multiplied by another number to find a product Departamento Matemáticas Sección Bilingüe

11. Product The answer to a multiplication problem Example: 6 x 2 = 12 The product is 12. Departamento Matemáticas Sección Bilingüe

12. Division The process of sharing a number of items to find how many groups can be made or how many items will be in each group; the opposite operation of multiplication Example: 6 ÷ 3 = 2 Departamento Matemáticas Sección Bilingüe

13. Dividend The number that is to be divided in a division problem Example: 35 ÷ 5 = 7 The dividend is 35. Departamento Matemáticas Sección Bilingüe

14. Divisor The number that divides the dividend Examples: 18 ÷ 3 = 6 The divisor is 3. Departamento Matemáticas Sección Bilingüe

15. Quotient The number, not including the remainder, that results from dividing Example: quotient Departamento Matemáticas Sección Bilingüe

16. 4 4 x 7 = 28 x 7 28 Factor A number that is multiplied by another number to find a product Examples: The factors are 4 and 7. Departamento Matemáticas Sección Bilingüe

17. Greater than (>) A symbol used to compare two numbers, with the greater number given first Example: 8 > 6 8 is greater than 6. Departamento Matemáticas Sección Bilingüe

18. Less than (<) A symbol used to compare two numbers, with the lesser number given first Example: 6 < 8 6 is less than 8. Departamento Matemáticas Sección Bilingüe

19. Square number The product of a number and itself; a number with the exponent 2 Example: Read 3 2 as "3 squared." 3 2 = 3 x 3 = 9 So, 3 2 = 9. 8 2 = 8 x 8 = 64 So, 8 2 = 64. Departamento Matemáticas Sección Bilingüe

20. because 25 = 5 x 5 = 25. Read: The square root of twenty-five equals five. Square root One of two equal factors of a number Example: Departamento Matemáticas Sección Bilingüe

21. Prime number A whole number greater than 1 that has only two factors; 1 and itself Example:factors Prime NumberFactors 21, 2 31, 3 51, 5 Not Prime NumberFactors 41, 2, 4 61, 2, 3, 6 91, 3, 9 Departamento Matemáticas Sección Bilingüe

22. Composite number A whole number that has more than two factors Example: 9 is a composite number since its factors are 1, 3, and 9. Departamento Matemáticas Sección Bilingüe

23. Prime factorization A number written as the product of all its prime factors Example: Departamento Matemáticas Sección Bilingüe 402 202 102 5 5 1

24. Greatest Common Factor (GCF) The greatest factor that two or more numbers have in common Example: 18: 1, 2, 3, 6, 9, 18 30: 1, 2, 3, 5, 6, 10, 15, 30 6 is the GCF of 18 and 30. Departamento Matemáticas Sección Bilingüe

25. Least Common Multiple (LCM) The smallest number, other than zero, that is a common multiple of two or more numbers Example: multiples of 6: 6, 12, 18, 24, 30, 36 multiples of 9: 9, 18, 27, 36, 45, 54 The LCM of 6 and 9 is 18. Departamento Matemáticas Sección Bilingüe
