### Math vocab 1

1. 1. Math Vocabulary 1 By L.D.
2. 2. What is a variable?A letter that represents a number, for examplethe variable in 5c is c. It can be positive ornegative.
3. 3. Pick out the Variable(s)!1. 5yt2. 6c + 8g3. 5c + 7c4. 4. 6u/4v
4. 4. Pick out the Variable(s)!1. 5yt 1. y&t2. 6c + 8g 2. c&g3. 5c + 7c 3. c4. 4. 6u/4v 4. u&v5. 7r 5. r
5. 5. What is a constant?A number like 4 or -5. That has no variable tospeak of.
6. 6. How many constants?1. 4y + 62. 7+53. -6x – 74. 9cde + cde
7. 7. How many constants?1. 4y + 6 1. One2. 7+5 2. Two3. -6x – 7 3. One4. 9cde + cde 4. None
8. 8. What is a coefficient?A number that has given up its "constant" statusand is with a variable like -5v. The -5 is thebearer of this terms name.
9. 9. Mini LessonWhenever you see a variable without a numbernext to it like y or n, then the coefficient isalways 1. This invisible one’s existence causes yto become 1y and n to become 1n.
10. 10. Find the coefficients1. 5v + 62. 5cdfd + 9n3. n+34. zx + 3
11. 11. Find the coefficients1. 5v + 6 1. 52. 5cdfd + 9n 2. 5&93. n+3 3. 14. zx + 3 4. 1&1
12. 12. What is the leading coefficient?It is the number/variable that is associated withthe highest exponent in a group. An example ofthis would be 56 + xc9. In this case c is theexponent of the biggest value.
13. 13. Which is the leading coefficient?1. 445+62. c+53. 55+664. 67 + 89
14. 14. Which is the leading coefficient?1. 445+6 1. 442. c+5 2. Both c and 53. 55+66 3. 64. 67 + 89 4. 8
15. 15. What are like terms?they are terms like 6c and 5c that share thesame variable. 6cx and 5c aren’t the samevariables so they aren’t like terms though.
16. 16. Are these like terms?1. 3x & x2. 6y & 5y3. 7y & 7t4. 8f & 0
17. 17. Are these like terms?1. 3x & x 1. yes2. 6y & 5y 2. yes3. 7y & 7t 3. no4. 8f & 0 4. no
18. 18. What is a monomial?Something (variable, a constant or coefficientand variable together) with a whole numberexponent (the exponents must always bepositive NEVER negative and they must never bevariables either). It has no adding or subtractionbut may have multiplying and dividing/fractionsif the former isn’t included.
19. 19. Is this a Monomial?1. 50c5yh92. 65x63. 67/64. 7 - 8f5. vy/66. r-57. c+c8. 7(-8)
20. 20. Is this a Monomial?1. 50c5yh9 1. yes2. 65x6 2. yes3. 67/6 3. yes4. 7 - 8f 4. no5. vy/6 5. yes6. r-5 6. no7. c+c 7. no8. 7(-8) 8. yes
21. 21. Words Not to Get Confused By1. Monotheistic2. Mono3. Monopoly4. Monogamy5. MonsoonEct…….
22. 22. What is a polynomial?A group of monomials added or subtracted ONEor more times. This creates binomials, trinomialsand so on.
23. 23. Are these polynomials?1. 6-62. -(6 + 5)3. 7x + c7 + 78u4. 7+8+95. 3/26. 5/x7. 7+8+9+x+c
24. 24. Are these polynomials?1. 6-6 1. no2. -(6 + 5) 2. yes3. 7x + c7 + 78u 3. no4. 7+8+9 4. yes5. 3/2 5. yes6. 5/x 6. no7. 7+8+9+x+c 7. yes

26. 26. What is a binomial?It is two monomials added or subtractedtogether.
27. 27. Are these binomials?1. 8+82. 6-7 + 6c + 83. 9+x4. -8sfsf/75. -76. 90
28. 28. Are these binomials?1. 8+8 1. yes2. 6-7 + 6c + 8 2. no3. 9+x 3. yes4. -8sfsf/7 4. no5. -7 5. no6. 90 6. no
