Order of Operations

Nice warm-up
A bit trickier
Go for it!
Master the order of operations (BODMAS/PEMDAS) through structured practice. Children learn why the sequence of calculations matters and apply brackets, division, multiplication, addition, and subtraction in the correct order. Essential preparation for secondary school maths.
Use the mnemonic BODMAS: Brackets, Orders, Division, Multiplication, Addition, Subtraction. Always work from left to right for operations of the same priority.
Brackets-first thinking is how spreadsheets, coding, and multi-step recipes stay consistent — order matters.
Who it suits: Order of operations games are most appropriate for Grades 5-7 (ages 10-13). These are typically introduced in Grade 5-6 and practised extensively in Grade 7 before secondary school. Students who find this difficult should first ensure they are fully fluent in each individual operation at the appropriate difficulty level.

Read each multi-operation expression carefully, apply the correct order of operations, and select the right answer. Remember: Brackets first, then multiplication and division, then addition and subtraction.

Order of operations is not just a rule to memorise — it is the shared language that makes mathematical expressions unambiguous. Without it, 2 + 3 × 4 could equal either 20 or 14 depending on which operation you do first. The agreed convention (multiplication before addition) ensures everyone gets the same answer. Mastering this in primary school is essential preparation for secondary maths, science, and computing.

The most common mistake is working strictly left to right, regardless of operation type (calculating 2+3×4 as (2+3)×4=20 instead of 2+(3×4)=14). A second common error is forgetting that multiplication and division are equal priority and should be evaluated left to right when they appear together. Encourage children to underline or circle the operation that should be done first before starting any calculation.
