136 . 23 + 136 . 17 - 40 . 36
= 136(23 + 17) - 40 . 36
= 136 . 40 - 40 . 36
= 40(136 - 36) = 40 . 100 = 4000
\(136.23+136.17-40.36=136\left(23+17\right)-40.36\)
\(=136.40-40.36=40.\left(136-36\right)\)
\(=40.100=400\)
136 . 23 + 136 . 17 - 40 . 36
= 136(23 + 17) - 40 . 36
= 136 . 40 - 40 . 36
= 40(136 - 36) = 40 . 100 = 4000
