• # ETT Level 1.2: Mathematics

## Learn how to solve basic math problems, calculate percentage, read graphs, and use simple geometric formulas.

1. Basic mathematics - Solve mathematical problems requiring simple addition, subtraction, multiplication, division, and raising numbers to exponential powers. Round to the appropriate number of significant digits, calculate percentages, read graphs, and use simple geometric definitions and formulas.
• Basic mathematics Review skills in addition, subtraction, multiplication, division, and percent.
• Percentages (%) One percent (1%) means 1 per 100.
• Exponential powers The exponent of a number says how many times to use the number in a multiplication.
• How to read graphs Graphs can be used to visually represent the relationship of data.
• The building blocks of geometry [Video] Understand and identify the undefined terms point, line and plane. Define segment, ray, angle, collinear, intersect, intersection and coplaner. Investigate postulates about points, lines and planes.
2. Basic metric units and conversions - Perform conversions to and from basic metric (SI) units.
