+104 I have 1 question (14+14-14*14/14)+(15+15*15/15)+(3+3-3*3/3)+
(13+13-13*13/13)+(24+24-24*24/24)= what
+9519 Define \(f(n) = n+n-n\times n \div n\).
Then your expression becomes \(f(14) + f(3)+f(13)+f(24)+15+15\times15\div 15\).
Simplifying f(n): \(f(n) = n+n-n\times n\div n = 2n - n = n\).
Therefore, the answer of the expression is \(14 + 3 + 13 + 24 + 15 + 15 \times 15 \div 15\), which is 84.
