# Course Syllabus for Numerical Mathematics

Course Description:
This course covers the basic arithmetic of whole numbers, exponents and roots, the order
of operations, fractions, decimals, percents, ratio and proportion , measurement and units,
integers, geometry, simple statistics and includes applications that use those topics.
Students will learn to work for part of the course without the use of a calculator.
3 (non-degree) credits Prerequisite: Placement test

Course Objectives
Students will achieve objectives with an asterisk * without the use of a calculator.
Upon successful completion of the course, the student will be able to:

*1. Use whole numbers in the four basic arithmetic operations (+, –, x, /).
*2. Use exponents and the order of operations.
*3. Use fractions in the four basic arithmetic operations.
*4. Use decimals in the four basic operations and round them.
*5. Calculate square roots of perfect squares and estimate square roots of decimals.
*6. Find ratios and solve proportions .
7. Calculate percents and solve the three kinds of percent problems.
8. Perform simple financial calculations, such as unit cost, discounts, balance.
9. Calculate simple interest and percents of increase/decrease and profit/loss.
10. Make and understand graphs and tables of data.
11. Make a histogram and find the mean, median and mode of sets of data.
12. Make measurements using the metric and U.S. systems and perform unit conversions
within and between the systems.
*13. Perform the four basic operations with integers and rational numbers.
14. Perform geometric calculations using angles, perimeter, area and volume.

Course Requirements

Students are expected to attend all scheduled classes, do the homework
assigned each day for the next class, complete graded worksheets, take tests and be active
participants in the class.

Student Evaluation and Testing
Student evaluation may include in-class or take-home testing,
class attendance, participation in class, graded worksheet assignments and notebook of
lecture notes and daily homework assignments. Your instructor will make clear his or her
grading system with an example in class.
