10 + 10 x 10 - 10 : 10 + 10 x 10 = 209
học tốt
10 + 10 x 10 - 10 : 10 + 10 x 10 = 190
k mk nha !!!! ^--^
10 + 10 x 10 - 10 : 10 + 10 x 10
= 10 + 100 - 1 + 100
= 110 - 1 + 100
= 109 + 100
= 209
10 + 10 x 10 - 10 : 10 + 10 x 10 = 290
k mk nha !!!!!!^---^
\(10+10\times10-10\div10+10\times10\)
\(=10+100-1+100\)
\(=110-1+100\)
\(=109+100=209\)
10 + 10 x 10 - 10 : 10 + 10 x 10
= 10 + 100 - 1 + 100
= 110 - 1 + 100
= 109 + 100
= 209
10+10*10-10:10+10*10
=10+100-1+100
=110-1+100
=109+100
=209
10+10.10-10:10+10.10
=10+100-1+100
=109+100
=209
