Answer 3

0+1+2+3+4+5+6+7+8+9+10 = (10+1)+(9+2)+(8+3)+(7+4)+(5+6) = 11x5 =55

tk nha !!!

Answer 4

nhầm nha

0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1

=11 x 5

=5 x 11

=78 - 23

=100 - 45

=55 - 0

=....

= 55

học tốt nha!

Answer 5

\(0+1+2+...+10=\left(0+10\right)\left[\frac{10-0}{2}+1\right]:2\)

\(=10\times11:2=55\)

Answer 6

0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

= (0 + 10) + (1 + 9) + (2 + 8) + (3 + 7) + (4 + 6) + 5

= 10 + 10 + 10 + 10 + 10 + 5

= 55

Answer 7

\(0+1+2+...+10\)

\(=\left[\left(10-0\right)\text{ : }1+1\right]\text{ x }\left(10+1\right)\text{ : }2\)

\(=10\text{ x }11\text{ : }2\)

\(=110\text{ : }2\)

\(=55\)

Answer 8

\(0+1+2+...+10\)

\(=\frac{\left[\left(10-0\right)\text{ : }1+1\right]\text{ x }\left(10+1\right)}{2}\)

\(=\frac{10\text{ x }11}{2}\)

\(=5\cdot11\)

\(=55\)

Answer 9

\(0+1+2+\cdot\cdot\cdot+10\)

\(=\frac{\left(10+0\right)\times11}{2}\)

\(=\frac{10\times11}{2}\)

\(=11\times5\)

\(=55\)

Answer 10

0+1+2+3+4+5+6+7+8+9+10=55

Answer 11

 Trả lời : 

= ( 0 + 10 ) + ( 1 + 9 ) + (2 + 8 ) + ( 3 + 7 ) + ( 4 + 6 ) + 5

=     10       +      10      +     10     +    10     +      10      +   5

=              55
