English for Mathematics

I studied an English for mathematics.
I studied mathematics in Japanese in Japan.

So, that is interesting for me.

+-*%

  • "+" plus, or add
  • "-" minus, or subtract
  • "*" multiplied by
  • "/" divided by

x + y : x plus y
x - y : x minus y
x * y : x multiplied by y
x / y : x divided by y. x: dividend, y: dividor

x^y : x to the y
x^2 : x squared

About bracket

( : opened bracket
) : closed bracket

For example,

2x^2 - 18x - 72 = 2(x^2 -9x -36) = 2(x + 3)(x - 12)

If I translate right side formula to English "two by opened bracket x plus 3 closed bracket by opened bracket x minus twelve closed bracket"

Ratio

x : y = x to y
