Multiplication and division of integers will be limited to 3 digit by 2 digit. Decimals will be limited to multiplying or dividing by a single digit
integer or a decimal number to 1 significant figure.
Candidates may use any algorithm for addition, subtraction, multiplication and division.
Candidates should know that some answers need to be rounded up and some need to be rounded down. Candidates should know that when
using approximations for estimating answers, numbers should be rounded to one significant figure before the estimating is done.

Notes: This is part of the core number work required across all units. Division in a given ratio is only tested in Unit 2.
Candidates should be able to use informal strategies, use the unitary method of solution, multiply by a fraction or other valid method.
Use of the quadratic formula will not be specifically tested on Unit 2 but candidates may use it to solve a quadratic equation, leaving the answers in surd form
where appropriate.
