Vinculum

maths

Today I learnt what was a vinculum.

It is the kind of thing you might learn when you help an eleven year old with his maths prior to a test. Yes I remembered what was a denominator and even a numerator but I had no idea the line that separated them was called a vinculum.

To spellcheck the word does not exist.

To google it is a tendon before it is something in mathematics.

Lately I have learnt how to do factor trees. It is something brand new to me. Not quite as much fun as learning that leaves transpire water from their surface just the same way we breathe. But. It’s maths. Quite fun really, but something I feel I have never done before. Did factor trees exist in the 1970’s? Where were factor trees when I was in grade seven? Between the rise of the white board and the demise of the blackboard did the triumphant factor tree emerge? Surely maths doesn’t change. Then, between straw-sucks of a liquid cereal breakfast, he tells me two negatives multiplied make a positive number. Are you sure? This rings a bell. I will have to check since I don’t do negative numbers. Pass me the iPad again. How is it that two negatives multiplied make a positive? Please don’t ask me why. My mind is spinning. It is only 7.30am. I wonder why negative numbers exist. You can’t have minus three apples any more than you can have minus six.

Then there is the school tie. If you want to wear a jumper – and it is cold outside – you need to wear a tie. But it looks ridiculous. No it doesn’t. Everyone will look ridiculous. It feels wrong. You’ll get used to it. Scream. Scream.

Under my breath and not under my breath – God save me. Save me from myself and my pettiness. Just wear the tie, so you can wear the jumper. Please.

If a submarine is 160 metres below the surface and then rises 90 metres and then submerges again by 170 metres how far is it below the surface? In my underlining you can see my purpose. I want it in cement. I want it drummed in. If I rub hard enough, underline often enough, say it louder it works, right? It makes me hate myself.

He trudges across the oval with the heaviest of chiropractor approved school bags. Must weigh ten kilos. He has the legs of a stick insect. There is dew on the oval. I call out looking good and a smirk creeps out. Don’t let her see it. Turn your body in case. Your morning track across the oval, like a giant snail trail.

I so wish the vinculum was just a tendon.

About Nicole Lobry de Bruyn

Born in the psychedelic sixties to hard working and conservative parents my sister and I grew up in sleepy suburban Perth, Western Australia. We played by the river, the beach and in the bushland of the cementary. I loved a chocolate Dachshund enough to make me want to become a veterinarian. I did. I became paralysed from the waist down when car hit tree. But not running, walking, standing or kneeling didn't prevent me being a vet. I am still a vet but would prefer to write and read and read and write about walking and not walking, feeling and not feeling, knowing and not knowing. So this is what happens when you enter thechookhouse.
