3. Terms or concepts related to addition SUM More than TOTAL Addends Increase PLUS

4. To find the missing addend 9 187 + N = 12 786 N = 12 786 – 9 187 ADDEND = Sum – other addend

5. Terms or concepts related to subtraction DIFFERENCE SUBTRAHEND MINUEND LESS LESS THAN MINUS DECREASEDIMINISH

6. To find the missing MINUEND N - 9 187 = 12 786 N = 12 786 + 9 187 MINUEND = Difference+ subtrahend

7. To find the missing SUBTRAHEND 29 187 - N = 12 786 N = 29 187 – 12 786 Subtrahend = Minuend - difference

8. Terms or concepts related to multiplication FACTORS PRODUCT MULTIPLES TIMES ( ) X TWICE, THRICEMultiplied by

9. To find the missing FACTOR 29 187 x N = 671 301 FACTOR =ProductOther factor N = 671 301 29 187

10. Terms or concepts related to division QUOTIENT DIVIDEND DIVISOR Divided by

11. To find the missing divisor DIVISOR =DividendQuotient N = 671 301 29 187671 301 N = 29 187

12. To find the missing DIVIDEND DIVIDEND = DIVISOR x QUOTIENT N = 23 x 29 187 N 23 = 29 187
