234 x 34 - 234 + 67 x 234
= 234 x 34 - 234 x 1 + 67 x 234
= 234 x ( 34 - 1 + 67)
= 234 x ( 33 + 67)
= 234 x 100
= 23400
234 x 34 - 234 + 67 x 234
= 234 x 34 - 234 x 1 + 67 x 234
= 234 x ( 34 - 1 + 67)
= 234 x ( 33 + 67)
= 234 x 100
= 23400
\(234\times34-234+67\times234\)
\(=234\times34-234\times1+67\times234\)
\(=234\times\left(34+67-1\right)\)
\(=234\times\left(101-1\right)\)
\(=234\times100\)
\(=23400\)
