*ab*in place of*a*Ã—*b*- 3
*y*in place of*y*+*y*+*y*and 3Ã—*y* *a*^{2 }in place of*a*Ã—*a*,*a*^{3 }in place of*a*Ã—*a*Ã—*a*,*a*^{2}*b*in place of*a*Ã—*a*Ã—*b*- a/b in place ofÂ
*a*Ã·*b* - coefficients written as fractions rather than as decimals
- brackets

A4 simplify and manipulate algebraic expressions (__including those involving surds__ **and algebraic fractions**) by:

- collecting like terms
- multiplying a single term over a bracket
- taking out common factors
- expanding products of two
**or more**binomials __factorising quadratic expressions of the form__;*x*^{2 }+*bx*+*c*, including the difference of two squares**factorising quadratic expressions of the form***ax*^{2 }*+bx+c*- simplifying expressions involving sums, products and powers, including the laws of indices
