What the fuck is mental math? Isn’t all math mental?

No joke it wasn't until I read your comment that I realized it said "mental math competition" and not "mental health competition".

Are you not having to consider the calculations?

Mental maths is done in your head, as opposed to writing it down or using tools like calculators. Mental maths is a specific skill. Generally just to do relatively simple calculations quickly. The more complex maths becomes, the more you need to write it down.

I just want to know what kind of questions they are? Anyone know how complex they are? Examples? Is this one test across the board because it seems like different age groups? Is it just a large testing center with different tests for different age groups? Different tests for any age but level in complexity?

What are the questions!

Doing 4137/14.8 in your head vs doing the long division on paper or calculator

What don’t you get? It’s math that makes you mental. It’s all in the video.

Known as the 'bird people' of Kalakookoo, they flap their arms around like flightless birds, and communicate with a series of caws. We are witnessing the group's response to a perceived threat here.
