If
ab=+10
bc+=20
ca+=+24
find a%2Bb%2Bc
ab=+10 => a=10%2Fb
ca+=+24=> a=24%2Fc
10%2Fb=24%2Fc
10c=24b
c=24b%2F10
c=2.4b
bc+=20
b%2A2.4b=20
b%5E2=20%2F2.4
b%5E2=8.333333333333333
b=2.886751345948129
c=2.4b
c=2.4%2A2.886751345948129
c=6.928203230275509
a=10%2Fb
a=10%2F2.886751345948129
a=3.464101615137754

check:
ab=3.464101615137754%2A2.886751345948129+=10
bc+=2.886751345948129+%2A6.928203230275509=20
ca+=6.928203230275509%2A3.464101615137754+=24
so, a%2Bb%2Bc will be
a%2Bb%2Bc=3.464101615137754%2B2.886751345948129%2B6.928203230275509
a%2Bb%2Bc=13.27905619136139
