Ensuring pupils understand the structure of the maths and not 'tricks' is so important. Encourage the use of correct language at all times

Absolute value - The absolute value of a number is its distance from zero. E.g. 5 and (-5) are both 5 away from zero and so both have an absolute value of 5.
Product - A product is the result of two or more numbers multiplied together.
