How do I make my mathemathics formula work

I been trying and trying to get my formula to work but it just won't calculate the right way..

Its the formula for braking distance.

The formula: (int(Speed.Text)/3.6^2) / (2*Car.Car.Friction*9.81)

Every single time it has calculated the wrong number

For example if i put the "Speed.Text as 120 and Car.Car.Friction as 0.9 i will get 3.14 and thats not right at all. It should have been 27.9

Could anyone correct the code so it calculates right?

Show me your .capx file

The game is not finished just making the event sheet working

I fixed the problem i just had to tweek the formula a bit so it would work,

The formula: (int(Speed.Text)/3.6)^2 /(2*9.81*Car.Car.Friction)

This is because of order of operations

int(Speed.Text) / 3.6 ^ 2 will do 3.6 ^ 2 first because exponential has a higher priority

Then by using parenthesis (int(Speed.Text) / 3.6) ^ 2 will first do the division, then the exponential
