Swift: Multiplication and brackets calculation doesn't work

Question

This is a example equation which I want to be solved:

let equation = (5-2) * (10-5) / (4-2) * (10-5)

print (equation)

//35

The result which is printed is 35. But the right result would be 1,5. Whats wrong?

Answer 1

This should work:

let numerator: Double = (5-2) * (10-5)
let denumerator: Double = (4-2) * (10-5)

Fist you calculate the numerator and denumerator. And finally the result:

print(result)
let result: Double = numerator/denumerator
//1.5
