\(a,\left(1267-196\right)-\left(1267-396\right)\)

\(=1267-196-1267+396\)

\(=\left(1267-1267\right)-\left(196-396\right)\)

\(=200\)

a, ( 1267 - 196 ) - ( 1267 - 396 )

= 1267 - 196 - 1267 - 396

= ( 1267 - 1267 ) - ( 196 - 396 )

=0 - ( - 200 )

= 0+ 200

= 200

3457 - 3442 = 15

Ai k mik , mik k lại !!!!!!!!!!!!!!!!!!!!!!!!!!!!

3457 - 3442 = 15

3457 - 3442 = 15

\(3457-27\cdot48-48\cdot73+6543\)

\(=\left(3457+6543\right)-48\left(27+73\right)\)

\(=10000-4800=5200\)

33 nha

k đi bạn

1267 - 1234 = 33 nha bạn

1267-1234=33

1259 + x = 3457

x = 3457 - 1259

x = 2198   

x=3457-1259

x=2198

3457 -1259 = 2198

4237nhân 18-3457nhân14=76266-48398=27868

\(\text{-(-800)+(1267-987)-(67-1987)}\\ =800+1267-987-67+1987\\ =800+\left(1267-67\right)+\left(-987+1987\right)\\ =800+1200+1000\\ =3000\)

=800 +1267 -987 -67 + 1987

= 800 + (1267-67) +(1987 -987)

= 800 + 1200 + 1900

= (800+1200) +1900

= 2000+1900

\(=\left(3457+6543\right)-48x\left(27+73\right)\)

\(=10000-4800=5200\)

#quankun^^

Trả lời:

\(3457-27\times48-48\times73+6543\)

\(=3457+6543-[48\times\left(27+73\right)]\)

\(=10000-48\times100\)

\(=10000-4800\)

\(=5200\)

Hok tốt!
