\(A=\frac{65+891+135+909}{731-47+69-253}\)
\(A=\frac{65+135+891+909}{731+69-47-253}\)
\(A=\frac{\left(65+135\right)+\left(891+909\right)}{\left(731+69\right)-\left(47+253\right)}\)
\(A=\frac{200+1800}{800-300}\)
\(A=\frac{2000}{500}=4\)
A = \(\frac{65+891+135+909}{731-47+69-253}\)
A = \(\frac{\left(65+135\right)+\left(891+909\right)}{\left(731+69\right)-\left(47+253\right)}\)
A = \(\frac{200+1800}{800-300}\)
A = \(\frac{2000}{500}\)
A = 4
\(A=\frac{65+891+135+909}{731-47+69-253}\)
\(A=\frac{5\times13+9\times9\times11+5\times27+9\times101}{17\times43-47+23\times3-11\times23}\)
\(A=\frac{5\times13+5\times27+9\times99+9\times101}{17\times43-47-11\times23+23\times3}\)
\(A=\frac{5\times\left(13+27\right)+9\times\left(99+101\right)}{17\times43-47-23\times\left(11-3\right)}\)
\(A=\frac{5\times40+9\times200}{17\times43-47-23\times8}\)
\(A=\frac{2000}{500}\)
\(A=4\)
