DATA TYPES

AT THE END OF THE LESSON, STUDENTS SHOULD BE ABLE TO:
1. identify variables; and
2. know its corresponding data type.

Technical Terms:

• Data Type - description of a specific data that can be stored in a variable, the amount memory the item occupies, and the operations it can be performed.

• Logical Operation - an operation that acts on binary numbers to produce a result according to the laws of Boolean Logic

• Rational Operation - is nothing more than a fraction in which the numerator and/or the denominator are polynomials
