Use mathematical formulas to explain how sugar water becomes sweeter by adding sugar as follows: Add sugar to sugar water, and the total volume of water remains unchanged.

Assume that there are m grams of sugar in the original sugar water and w grams of water, then the original sugar concentration is m/ (m+w). Now add n grams of sugar, then the sugar concentration is (m+n)/(m+

n+w)(m+n)/(m+n+w)-m (m+w)=nw/(m+n+w)(m+w)>0 It can be seen that the concentration of sugar after adding sugar is greater than the original

The concentration of sugar water, so adding sugar to sugar water will make it sweeter.
