k mình nha!

trả lời

345-345=0

123+123=246

hok tốt

345-345=0

123+123=246

học tốt

=345*(123-23)=345*100=34500

345x123-345x23

=345x(123-23)

=345x100

=34500

345 x 123 - 345 x 23

= 345 x ( 123 - 23 )

= 345 x 100

= 34500

x + 123 = 234 + 345

x + 123 = 579

x = 579  - 123

x = 456

x + 123 = 234 +345

x + 123 = 579

x = 579 - 123

x = 456

x + 123 = 234 + 345

x + 123 = 579

x = 579 - 123 

 x = 456

a) x – 123 = 345                                                         b) x + 254 = 665

         x      = 345 + 123                                                    x          = 665 – 254

         x      =  468                                                                x       = 211

123 x 45 - 345 + 1234

= 5535 - 345    +1234

=    5190          + 1234

=         6424

\(123\times45-345+1234\)

\(=492-345+1234\)

\(=147+1234\)

\(=1381\)

123 x 45  - 345 + 1234

=5535 -345 + 1234

=5190 + 1234

=6424

123+345+456-123-2017-345

= ( 123 - 123 ) + ( 345 - 345 ) - ( 123 + 2017 ) 

= 0 + 0 - 2140

= -2140

Trả lời :

( 123 + 345 ) + ( 456 - 123 ) - [ 2017 - ( - 345 ) ]

= 123 + 345 + 456 - 123 - 2017 - 345

= 123 + 345 + 456 + ( - 123 ) + ( - 2017 ) + ( - 345 )

= [ 123 + ( - 123 ) ] + [ 345 + ( - 345 ) ] + [ 456 + ( - 2017 ) ]

= 0 + 0 + ( - 1561 )

= - 1561
