7. CONSTANTS, VARIABLES AND ALGEBRAIC EXPRESSIONS

8. CONSTANT Are NUMBERS that have fixed values. 3a CONSTANT

9. VARIABLES Are SYMBOLS AND LETTERS that may take one or more than one value 3a variable

10. TERM Is a CONSTANT, VARIABLE , A PRODUCT OR A QUOTIENT OF CONSTANTS AND VARIABLES . Terms are separated by the symbols + and - .

11. TERM Monomials Binomials Trinomials Multinomials CLASSIFICATION OF TERMS

12. SIMILAR TERMS DISSIMILAR TERMS TYPES OF TERMS ACCORDING TO LITERAL COEFFICIENT TERM

13. Is a variable, a constant or a combination of both which may be related by any of the four fundamental operations ALGEBRAIC EXPRESSIONS
