Topic: Algebraic Manipulation and Formulae (Higher - Unit 3)

Specification References: N4.1 N4.1 Distinguish the different roles played by letter symbols in algebra, using the correct notation

Candidates should be able to:

• use notations and symbols correctly
• understand that letter symbols represent definite unknown numbers in equations, defined quantities or variables in formulae, and in functions they define new expressions or quantities by referring to known quantities

Notes

This is part of the core algebra work required across all units.

The core algebra work will be assessed so that it is linked to other specification references within this unit.

Candidates will be expected to know the standard conventions;

for example, 2x for  and  or  for
x2 is not acceptable for
