在算式里添上括号,使等式成立①80-56*4+4=62 ②80-56*4+4=3 ③80-56*4+4=10 ④80-56*4+4=73 顺便说一下,我不会打除号,就用了*代替

问题描述:

在算式里添上括号,使等式成立
①80-56*4+4=62 ②80-56*4+4=3 ③80-56*4+4=10 ④80-56*4+4=73 顺便说一下,我不会打除号,就用了*代替

小键盘的"/"就是除号
80-(56/4+4)=62
(80-56)/(4+4)=3
(80-56)/4+4=10
80-56/(4+4)=73

80-(56÷4+4)=62 (80-56)÷(4+4)=3 (80-56)÷4+4=10
80-56÷(4+4)=73

①80-56*4+4=62
80-(56*4+4)=62
②80-56*4+4=3
(80-56)*(4+4)=3
③80-56*4+4=10
(80-56)*4+4=10
④80-56*4+4=73
80-56*(4+4)=73
注:*代表除号

80-(56÷4+4)=62
(80-56)÷(4+4)=3
(80-56)÷4+4=10
80-56÷(4+4)=73

80-(56/4+4)=62
(80-56)/(4+4)=3
(80-56)/4+4=10
80-56/(4+4)=73

80-(56/4+4)=62
(80-56)/(4+4)=3
(80-56)/4+4=10
80-56/(4+4)=73

注意,*应该表示乘
①80-(56÷4+4)=62
②(80-56)÷(4+4)=3
③(80-56)÷4+4=10
④80-56÷(4+4)=73

80-(56/4+4)=62
(80-56)/(4+4)=3
(80-56)/4+4=10
80-56/(4+4)=73
