For example: Fa=1/8 Fb (F A equals to one eighth times F B) A=0.01B or 0.001B or 10^-5B (A equals to point zero one times B or point zero zero one times B or 10 TO a factor of negative 5) π/3=60° （pi DIVIDED BY THREE equals to sixty degrees） I'd like to know how you will express them. Thank you from the bottom of my heart. Generally we don't use fractions when part of a more complex calculation (than subtraction and addition) so you might say 1/4 - 1/8 a quarter minus an eigth but Pi/3 is not a third of pi, it is Pi divided by three.

I think different English speaking countries say it differently, but this is how we say it in my country Fa=1/8 Fb (F A equals to one over eight times F B) A=0.01B or 0.001B or 10^-5B (A equals to point zero one B or point zero zero one B or 10 to the power of negative 5b) π/3=60° （pi over three equals to sixty degrees）

Perhaps u can watch some of the math videos on the Khanacademy Youtube channel, that will teach you how to say Math terms

There shoul be Math English as a field))
