very simple question, regarding maths in java

Hi, i am just starting to learn javascript, so i am probably doing something very simple wrong. i have read a lot of articles on maths in java, but cant find anything simple enough for my problem. I am looking for how to get an IF statement to give me the correct output. I am trying to get it to give me a result for a weeks pay, taking that the code worked before i tried to add the IF statement, to make it that if HoursWorked >= 20, the rate of pay would be an extra $2 p/hr. i had the following code to make this work

but, as simple maths will tell you, the answer is not $3800!! can anyone please tel me what silly mistake i am making here please :) sorry to be asking something so simple, but my teacher is away for the weekend and i have just started this module in my course.

Java != Javascript.
I'll assume you meant what you said when you said javascript so I'll move this to the Javascript forum.

re: very simple question, regarding maths in java

what are the HoursWorked and RateOfPay values, before the calculation?

re: very simple question, regarding maths in java

i dont even know how it is getting the result it is, 3800... all the other tasks i have been doing have been working fine, even the more complicated ones.

re: very simple question, regarding maths in java

that explains it…
the + operator does not only adds numbers, it also concatenates strings. and that’s what’s happening.

better use
