优质解答
(5＋5)×((5－5)×5)
=(5＋5)×(0×5)
=(5＋5)×0
=10×0
=0
(5＋(5－5)×5)÷5
=(5＋0×5)÷5
=5÷5
=1
(5×5－5)÷(5＋5)
=(5×5－5)÷10
=20÷10
=2
(5×5－(5＋5))÷5
=(5×5－10)÷5
=15÷5
=3
(5＋5－5)×5÷5
=5×5÷5
=5
(5＋5)×((5－5)×5)
=(5＋5)×(0×5)
=(5＋5)×0
=10×0
=0
(5＋(5－5)×5)÷5
=(5＋0×5)÷5
=5÷5
=1
(5×5－5)÷(5＋5)
=(5×5－5)÷10
=20÷10
=2
(5×5－(5＋5))÷5
=(5×5－10)÷5
=15÷5
=3
(5＋5－5)×5÷5
=5×5÷5
=5
