Factorising is the opposite of expanding brackets. When we factorise, we put brackets in. In the previous session we looked at the expression x(y + 1). If we expand the brackets w...

The expression xy means x times y. But what are we to make of the expression x(y+1)? This must mean x times (y+1) which, in turn, means x times y plus x times 1 - everything outsi...

Algebra is about solving equations. Or to be more precise, we solve equations using algebra. One of the most simple ideas in algebra is the idea of collecting like terms, or simpl...

Consider the linear equation 2x + 1 = 5 If we solve this equation we get x = 2. What happens if we plug x = 2 into the left hand side of the equation? We get 5. What happens if w...
