Frequently asked questions
What is Algebra?
Algebra covers Notation, vocabulary and manipulation, Graphs, Solving equations and inequalities, and Sequences in GCSE Edexcel Foundation Maths. 24 lessons in 4 subtopics.
How do you substitute into the area of a trapezium formula?
The area of a trapezium is A = 1/2(a + b)h, where a and b are the parallel sides and h is the perpendicular height. The Substituting into and Interpreting Formulae notes cover this in full.
How do you expand and simplify brackets?
To expand and simplify, expand each bracket, write out all the terms, then collect like terms. The Collecting Like Terms and Basic Algebraic Operations notes cover this in full.
What is an expression in maths?
An expression is a mathematical phrase made up of one or more terms connected by operations such as +, -, × and ÷. The Understanding Algebraic Language notes cover this in full.
How do you expand triple brackets?
To expand three brackets, expand two first, then multiply the result by the third. The Expanding and Factorising Expressions notes cover this in full.
What is an inequality in maths?
An inequality compares two expressions using a symbol such as ≤, ≥, greater than or less than, so its solution is a set of values rather than a single number. The Understanding Algebraic Language notes cover this in full.
How do you expand a single bracket?
To expand a single bracket, multiply the outside term by every term inside the bracket, not just the first one. The Collecting Like Terms and Basic Algebraic Operations notes cover this in full.
How do you find the y-intercept?
The y-intercept is where the line crosses the y-axis, so read off the y-value when x = 0. The Gradients and Intercepts of Linear Functions notes cover this in full.
What is an equation in maths?
An equation is a mathematical statement that two expressions are equal, written with an = sign. The Understanding Algebraic Language notes cover this in full.
