1000 + 2000 x 50 / 2 = 51000
900 + 120 - 56 x 3 = 852
1000 + 2000 x 50 / 2 = 1000+ 50000 =51000
900 + 120 - 56 x 3 = 900+120-168= 1020-168= 852
tk mik nha
\(1000+2000\times\frac{50}{2}=1000+2000\times25=1000+50000=51000\)
\(900+120-56\times3=900+120-168=1020-168=852\)
Học tốt !!!
1000 + 2000 * 50/2 = 51000
900 + 120 - 56 * 3 = 852
1000 + 2000 x \(\frac{50}{2}\) = 1000 + 50000
= 51000
900 + 120 - 56 x 3 = 1020 - 168
= 852
.......................
1000 + 2000 x 50 : 2
= 1000 + 100000 : 2
= 1000 + 50000 = 51000
900 + 120 - 56 x 3
= 900 + 120 - 168
= 1020 - 168 = 852
\(1000+2000+\frac{50}{2}\)
\(=1000+2000+25\)
\(=3000+25=3025\)
\(900+120-56\times3\)
\(=900+120-168\)
\(=1020-168=852\)
1000 + 2000 x 50 : 2 = 1000 + 2000 x ( 50 : 2 )
= 1000 + 2000 x 25 = 1000 + ( 2000 x 25 )
= 1000 + 50000
= 51000
1000 + 2000 x 50 : 2 = 5100
900 + 120 - 56 x 3 =1188
