3. Definitions:
Constant
 Any number is a constant such as 3, 5,8,15 and 27.
 Any symbol that has a fixed value is a constant such as 𝜋 ,since its
value is approximately 3.1416.
Variable
 Any letter is a variable such as 𝑥, 𝑦, 𝑧, 𝑎, 𝑏, 𝑐, 𝑛.
 Any symbol that used to represent an unknown number such as
, _____.
Note: Variable is used to represents the unknown number.

4. Definitions:
Numerical Expression
A numerical expression is a mathematical phrase that uses
numerals and operation symbols.
Example: 4 + 8 , 5 × 11 , 6 ÷ 3
Algebraic Expression
