I think the professional preparing this video is unaware of mathematic laws..

2,386 PointsYes you are Right . Infact, Most of us haven't done evaluating a value of complex expressions in mathematics . When it comes to programming it is always the needy feature that programmer has to know it must .

Treehouse Moderator 145,860 PointsActually Saud Alfaris, that is incorrect.
The modulo operator is not just a function of Swift. It is used by almost every language and is a mathematical expression used in mathematics. You can read about it here if you wish. So, Swift is only following the rules of mathematics, not its own in this case.

2,386 PointsNo, He is Correct with All Known mathematic Laws . This is how an expressions is evaluated in traditional mathematics . Off course it might seem odd to You , but this is the way that compilers follow the rules of mathematics in evaluating the expression based on the precedence Level of the arithmetic operators . Remember some operators in expressions may be evaluated Either from Left to right / right to Left . But Arithmetic Operators Always starts evaluating from left to right only .
