Answer 1

100+101+102+103=406

Answer 2

100+101+102+103=406

Answer 3

100 + 101 + 102 + 103

= (100 + 103) + (101 + 102)

= 203              +     203

= 1                   + 1

= 2

Answer 4

 100+101+102+103=406

Answer 5

100+101+102+103=406

Answer 6

100 + 101 + 102 + 103 

= 100 + 0 + 100 + 1 + 100 + 2 + 100 + 3 

= ( 100 + 100 + 100 + 100 ) + ( 0 + 1 + 2 + 3 ) 

= 400 + 6 

= 406 

Answer 7

100 + ( 101 + 102 ) + 103

= 100 + 203 + 103

= 100 + ( 203 + 103 )

= 100 + 306 =406 

Answer 8

=100 +(101+102)+103 

=100+203+103

=100+306

=406

Answer 9

100 + 101 + 102 + 103 

= 100 + 0 + 100 + 1 + 100 + 2 + 100 + 3 

= ( 100 + 100 + 100 + 100 ) + ( 0 + 1 + 2 + 3 ) 

= 400 + 6 

= 406 

Answer 10

100 + 101 + 102 + 103

= ( 100 + 100 + 100 + 100 ) + ( 1 + 2 + 3 )

= 400 + 6 

= 406 

Chúc bạn học giỏi nha !!!

Answer 11

100+101+102+103

=(101+103)+(101+102)

=203+203

=203*2

=406

Answer 12

100+101+102+103

=100+100+1+100+2+100+3

=(100+100+100+100)+(1+2+3)

= 400 + 6

=406

Chúc bạn học tốt !!

Answer 13

100 + 101 + 102 + 103

= 201 + 102 + 103

= 303 + 103

= 406

Answer 14

100 + 101 + 102 + 103

= ( 100 + 103 ) + ( 101 + 102 )

= 203 + 203 

= 203 . 2

= 406

Answer 15

100 + 101 + 102 + 103 = 201 + 205 = 406

Answer 16

\(100+101+102+103\)

\(=\left(100+103\right)+\left(101+102\right)\)

\(=103+103\)

\(=103\times2\)

\(=206\)

Answer 17

xin lỗi tớ làm lộn

sửa: \(100+101+102+103\)

\(=\left(100+103\right)+\left(102+101\right)\)

\(=203+203\)

\(=203\times2=406\)

Answer 18

100 + 101 + 102 + 103

= 100 + 0 + 100 + 1  + 100 + 2 + 100 + 3

= ( 100 + 100 + 100 + 100 ) + ( 0 + 1 + 2 +3 )

= 400 + 6

= 406

Answer 19

\(100+101+102+103\)

\(=100+100+1+100+2+100+3\)

\(=\left(100+100+100+100\right)+\left(1+2+3\right)\)

\(=100\times4+6\)

\(=400+6\)

\(=406\)

Answer 20
