Solve step by step: 3 × 3 + 3 ÷ 3 – 3
Have you ever heard the mathematical expression 3 × 3 + 3 ÷ 3 – 3 and not known where to start? Don’t worry! Thanks to the PEMDAS method (or BEDMAS, depending on the country), everything becomes clear. And as a bonus, it is a great exercise to strengthen your reasoning skills !
What is Bedmas?
This is a very handy mnemonic to remember the order in which you need to solve a mathematical expression:
- B-ketchere ( parents )
- Exhibitors
- Section
- Multiplication
- And the recipient
- Subtract ( subtract )
In French, we often simply call it the rule of operational priorities :
We always start with parentheses , then powers , followed by division and multiplication from left to right , and finally addition and subtraction , also from left to right .
