567 + 567 . 101 - 567 - 567
= 567 ( 101 - 1 )
= 567 . 100
= 56700 nhé bạn

567 x 34 + 567 x 67 x 567 - 567
= 567 x 34 + 567 x 37989 - 567
= 567 x ( 34 + 37989 ) - 567
= 567 x 38023 - 567
= 21559041 - 567
= 2558474

\(-567-\left(-113\right)+\left(-69\right)-\left(113-567\right)\)
\(=-567+113+\left(-69\right)-113+567\)
\(=\left(-567+567\right)+\left(113-113\right)+\left(-69\right)\)
\(=\left(-69\right)\)
\(-567-\left(-113\right)+\left(-69\right)-\left(113-567\right)\)
\(=-567+113-69-113+567\)
\(=\left(-567+567\right)+\left(113-113\right)-69\)
\(=0+0-69=-69\)

\(\frac{1234\times567-667}{567+1234\times566}=\frac{1234\times\left(566+1\right)-667}{567+1234\times566}=\frac{1234\times566+1234-667}{567+1234\times566}\)
\(=\frac{1234\times566+567}{567+1234\times566}=1\)
