This Unit focuses on the mathematics used every day in our communities to measure, compare and present information numerically. There is an emphasis on the development of real numbers and their everyday usage in learning mathematics.

This is the first unit in the series of General Mathematics for Grade 11. As you go along with the unit, you will find lessons and activities which will help you make use of appropriate techniques and instruments to estimate and calculate physical quantities. In addition, this unit will also lead you to apply knowledge of numbers and their relationships to investigate a range of different context.

11.1.1:    BASIC NUMERACY

This topic introduces real numbers in complex number field; and revises multiples and factors, operations with fractions, estimation and error,  and writing digits correct to specified significant digits.

11.1.2:     LAWS OF INDICES

This topic revises basic concepts of indices, and laws of indices. The topic provides the basis to study logarithms and exponential functions and graphs.

11.1.3:      SURDS

This topic evolves from laws of indices; it expands on to application of basic operations on surds. It explains the approximation and exact values of quantities and measurements.

11.1.4:      UNITS OF MEASUREMENT

The topic covers Metric and Imperial Measurement. Then expands on to quadratic equations and graphs. It also discusses inequalities and systems of inequalities.
