Morphology

one + hundred + seventy

The meaning '170' is directly and transparently derived from combining 'one' + 'hundred' + 'seventy' following standard numeric composition (100 + 70). This arithmetic, compositional pattern is regular in English (and similar in many languages), so a B1 learner who knows the constituent numerals will understand the MWE.

Etymology

One hundred seventy is made from one hundred plus seventy, so picture a pile of 100 apples and then 70 more added to it. That's why it means '170'.
