234+567= bao nhiêu ?
123+123*234+234*345+345*456+456*567+567*678+678*789+789
567 X 234 - 234 X 542 + 234 =
567 x 234 - 234 x 542 + 234
= 234 x ( 567 - 542 + 1)
= 234 x 26
= 6084
567x234-234x542+234=234x(567-542+1)=234x26=6084
Ta có: 567 x 234 - 234 x 542 + 234 = 567 x 234 - 234 x 542 + 234 x 1
= 234 x (567 - 542 + 1)
= 234 x 26
= 6084
