Question 286903
Take things one at a time. First, let's compute {{{1/3+(-5/6)}}}. This is the same as {{{1/3-5/6}}}


*[invoke fractions_solver 1, 5, "-", 3, 6]



Since {{{1/3-5/6=-1/2}}}, the problem {{{1/3+(-5/6)+(-1/2)}}} simplifies to {{{-1/2+(-1/2)}}} (I replaced the first two terms with {{{-1/2}}})



------------------------------------------------------------------------


Now let's compute {{{-1/2+(-1/2)}}}. This is the same as {{{-1/2-1/2}}}



*[invoke fractions_solver "-1", 1, "-", 2, 2]


note: {{{-1/1=-1}}}



So {{{-1/2+(-1/2)=-1}}}



So finally, this means that {{{1/3+(-5/6)+(-1/2)=-1}}}
