Worst maths teacher in the world

That’s me. I’m so bad at maths I have to mark the numbers one to ten on my fingers and then of course I can only count up to 10.
What do you want to learn maths for anyway? Your parents haven’t had to count up to 10 since primary school. Probably a good job to cos if they wanted to learn how to now they might ask me to teach them and I’M AWFUL!
