Javascript simple math error -

I do not understand what this is, though math is never my specialty, so any help would be appreciated. Is performed. My simple equation is in two parts: Answer 1) 226 - [value] multiplied by 9.

Answer 2) 226 - By multiplying [value] .55

If you use 40 as the input value, then my calculator says: < P> Answer 1) 226 - 40 = 186 * .9 = 167.4

Answer 2) 226 - 40 = 186 * .55 = 102.3 < / P>

But my code says:

Answer 1) 190

Answer 2) 204

My code:

  HTML: & lt; Input id = "hr" size = "4" value = "" /> gt; & Lt; Span id = "number" & gt; & Lt; / Span & gt; Answer 1 & lt; Strong & gt; & Lt; Span id = "answer1" & gt; & Lt; / Span & gt; & Lt; / Strong & gt; & Lt; Br> Answer 2 & lt; Strong & gt; & Lt; Span id = "answer2" & gt; & Lt; / Span & gt; & Lt; / Strong & gt; & Lt; / P & gt; & Lt; A href = "#" square = 'THR' & gt; Click to compute & lt; / A & gt; Script: & lt; Script type = "text / javascript" & gt; $ ('A.THR'). Click (function () {var value = parseInt ($ ("#HR") .val ()); $ ("# answer1") .html (226 - value * 0.9); $ ("# answer2"). Html (226 - value * 0.55); return back;}); & Lt; / Script & gt;    
 
 
 You are forgetting the operation order. Mostly predecessor compared to multiplication / addition. Place brackets around your  226-value   
  $ ("# answer1") .html ((226-value) * 0.9); $ ("# Answer2"). HTML ((226 - value) * 0.55);   
 Reading your question again, I do not know what exactly is your desired outcome. If you want to multiply first and then subtraction, then you do not need brackets, though it To clarify,  226 - (value * 0.9)  can be helpful in writing. What is happening on your calculator, though it is that you are typing  226 - value  and after you increase the result of your decimal number then the above code,  (226 - value) * 0.9 < / Code> indicates your typing, can help to say that what you are trying to do with interval user perspective, to determine where your brackets are.
