Order of Operations

This is a very useful way to explore how calculations are affected by the order of operations.

You need a pen and paper

When thinking about the order of operations, or BODMAS, it is very important to be clear what each step actually means.

Watch this video, from tecmath.

Now, together, work through some of the 'tricky' equations tecmath shared.

For example:


See if you can break the equations down into separate steps?

Is this helpful?

Do you get the same answers?

Some people think if brackets were always used the order of operations would be much easier to see. What do you think?

Can you make up some different problems where the answer changes if the operations are done in a different way?
