\(25-\left(20-10\right)=25-10=15\)
\(80-\left(30+25\right)=80-30-25=50-25=25\)
\(125+\left(13+7\right)=125+20=145\)
\(416-\left(25-11\right)=416-14=402\)
\(25-\left(20-10\right)\)
= \(25-10\)
= \(15\)
\(80-\left(30+25\right)\)
= \(80-55\)
= \(25\)
\(125+\left(13+7\right)\)
= \(125+20\)
= \(145\)
\(416-\left(25-11\right)\)
= \(416-14\)
= \(402\)
\(25-\left(20-10\right)\)
\(=25-20+10\)
\(=15\)
\(80-\left(30+25\right)\)
\(=80-30+25\)
\(=75\)
\(125+\left(13+7\right)\)
\(=125+13+7\)
\(=145\)
\(416-\left(25-11\right)\)
\(=416-25+11\)
\(=402\)
ta có \(80-\left(20-10\right)=80-20+10\)
\(=60+10\)
\(=70\)
ta có \(125+\left(13+7\right)=125+13+7\)
\(=125+20\)
\(=145\)
ta có \(416-\left(25-11\right)=416-16\)
\(=400\)
25−(20−10)
=25−10
=15
80−(30+25)
=80−30−25
=50−25
=25
125+(13+7)
=125+20
=145
hok tốt !
Nhầm ý nầy làm lại:
\(80-\left(30+25\right)\)
\(=80-30-25\)
\(=25\)
25 - ( 20 - 10 )
= 25 - 10
= 15
80 - ( 30 + 25 )
= 80 - 55
= 25
125 + ( 13 + 7 )
= 125 + 20
= 145
416 - ( 25 - 11 )
= 416 - 14
= 402
~ Năm mới vui vẻ ! ~
