The BIDMAS rule book 1 and 2

BIDMAS is an acronym used to tell you the correct order to complete a calculation when there are different operations. Most importantly, it stands for Brackets, Indices , Division, Multiplication, Addition and Subtraction.

Learning Objective

• Discuss and follow the steps in using the BIDMAS rule.
• Calculate with two operators.
• Work out calculations with two operators and indices.
• Calculate with three operators brackets and indices.

Learning Outcome

Students completing this workbook will be able to:

• Use the order of operations including brackets.
• Utilize the BIDMAS rule to evaluate a string of numbers with different operators in the same sum.

Recommended Level 

This workbook will help pupils to build the knowledge and skills expected to match the new National Curriculum for years 7. Although, pupils in years 8 and 9 can benefit from this workbook because they will be able to use this as a refresher. 

The advantage of using the Alphareach BIDMAS workbooks

The Alphareach BIDMAS workbooks makes explicit the meaning of the BIDMAS rule and emphasise the importance of it with examples. The workbooks give pupils model examples and further supports them by giving step by step guided instructions in how to calculate using the BIDMAS rule. This makes it easy for parent or teacher/tutor to support the learner.

There are plenty of practice examples for pupils to learn the concept and apply them using graded examples in order of difficulty.

The mathematical tasks in the BIDMAS book 1 and 2 are based on the variation theory. As a result, pupils deepen their understanding of the concept of the BIBMAS rule. By using plenty of follow up sums to develop their skill and improve confidence.

To conclude, to maximise the benefit for the learners, it is recommended that both BIDMAS rule book 1 and 2 are used.
