The student consistently and correctly used mathematical notation, symbols, and terminology. Computer notation is present only if software-generated, with clear indication. Key terms/variables are defined and explained when first introduced. Additional terms are defined in detail in appropriate places. Multiple forms of mathematical representation are present but used only if appropriate. All mathematical calculations are explained, any data presentation is described, and the degree of accuracy is stated for any rounded values. Results are rounded only at the end of the calculations thread. The student used a deductive method and set out logical proofs where appropriate. The graphs, tables, and diagrams are labeled (titled and numbered) at the bottom. However, the introduction lacks a description of the used mathematics, therefore brief explanations of the main concepts applied are also missing from the introduction.
