**WAEC 2020 MATHEMATICS SYLLABUS GENERAL GUIDE.**

For all papers which involve mathematical calculations, mathematical and statistical tables published for WAEC should be used in the examination room. However, the use of non-programmable, silent and cordless calculator is allowed.

The calculator must not have a paper printout. Where the degree of accuracy is not specified in a question the degree of accuracy expected will be that obtainable from the WAEC mathematical tables.

**Trigonometrical tables**

in the pamphlet have different columns for decimal fractions of a degree, not for minutes and seconds.

No mathematical tables other than the above may be used in the examination. It is strongly recommended that schools/candidates obtain copies of these tables for use throughout the course.

Candidates should bring rulers, protractors, pair of compasses and set squares for all papers.

They will not be allowed to borrow such instruments and any other materials from other candidates in the examination hall. It should be noted that some questions may prohibit the use of tables and /or calculators. The use of slide rules is not allowed.

Graph paper ruled in 2 mm squares, will be provided for any paper in which it is required.

**UNITS**

Candidates should be familiar with the following units and their symbols.

Length

10000 millimetres (mm) = 100 centimetres (cm) = 1 metre (m)

1000 metres = 1 kilometre (km)

Area
