The Vanishing One
This joke plays on spelling. Here if we are trying to make "one" vanish we add "g" to make it "gone". That's because "g" + "one" = "gone". And gone is a synonym for vanished!
With a couple of jokes in one, this covers everything from Calculus to algebra. From the top then! In Calculus, a derivative is a way to notate a rate of change, in English, a derivative is an imitation of another's work. So this pun isn't very original. In trigonometry, there are many aspects that are graphed to be understood, from triangles to sine waves. In English, graphic can mean vivid or explicit detail. This pun isn't appropriate for younger audiences. In algebra, formulas are found. In English, formulaic can mean predictable. This pun is downright boring. But the statistics pun is here to save the day! Unlike it's fellow math puns, the statistics pun is an outlier, meaning it doesn't match what most other puns in this list are.
Who is the largest knight at the round table? Sir Cumference! How did he get so big? He ate too much pi!
The first part of the joke relates to the round table (which we're assuming has the shape of a circle) and the similarity of the sounds of circumference (the distance around a circle) and Sir Cumference (a rather portly knight). Sir Cumference became so round by eating too much pi (the homonym of the most delicious pie!). The mathematical pi is used in the calculation of the circumference of a circle. Allowing this joke to come full circle!
The function f(x) = |x| is the absolute value function. It represents a number's distance from 0. Since distance is always a positive number, the absolute value function returns positive numbers. Definitely avoiding negativity!
You make me ten times better! I'm nothing without you!
Place value is the key to this joke. Alone the 1 represents a single unit. Pairing 1 and 0 together indicates 1 group of ten units and 0 groups of single units, 10 times more than the single unit! Taking away the 1 out 10 leaves 0 units, nothing without the 1!
