The different ways in which numbers slide up, down, sideways, diagonally.
Is the example in the post part of the fifth type of arithmetic?
Addition +
Subtraction -
Multiplication x
Division /
Modulo %
The first time I learned about modulo as its’ own branch of arithmetic was long out of school already, I had only hazily heard of it, on a PBS Nova documentary in the 1990s about Fermat’s famous theorem and when it was proven after centuries of failed tries.
Yeah we just learned “by” was a standard term for multiplication. So increased by 80% was just 1.8 times whatever you started with. “Divide by” meaning multiply inversely
Language translating to artithmetic.
I’m sure it doesn’t always line up, as we change language quite often.

No it’s not modulo, it’s how to talk about increasing a number by a percentage of the number.
