How to teach it

- Then the exponents (powers).
- Then multiply and divide, from left to right, whichever comes first.
- Then add and subtract, from left to right, whichever comes first.
Questions teachers ask
- Is it BEDMAS or PEMDAS?
- Both name the same rule. Canadian classrooms say BEDMAS: brackets, exponents, division and multiplication, addition and subtraction. US classrooms say PEMDAS: parentheses, exponents, multiplication and division, addition and subtraction. Multiplying and dividing are done together from left to right, and so are adding and subtracting.
- What grade learns the order of operations?
- Brackets come in around Grade 5, exponents in Grade 6, and integers in Grade 7. In Alberta, Grade 6 evaluates expressions with brackets and powers, and Grade 7 uses positive decimals.
