The first thing that you notice when starting to learn Hebrew is its reading and writing direction. This introduction-level lesson focuses on Modern Hebrew grammar rules.ġ.
Note: If you’re looking for Biblical Hebrew grammar, see this article. So, this friendly Hebrew Grammar Rules is a quick little introduction for you. And, you want to brush up Hebrew Grammar basics. The left-most statements are executed first, but each individual statement is parsed as described above.Either you started learning or want to learn Hebrew.

Which gives 0 in traditional mathematic execution order. The easiest way to demonstrate how this affects things is: 84 - 12 - 1 - 13 - 28 - 9 - 6 - 15
Since it is inspired by traditional mathematics then it follows f(g(x)):į g x means apply g to x and then apply f to the result of that, hence right to left. +/2 3 4×1 0 ¯1 ⍝ Equivalent expression for vectors Or the inner product: 2 3 4+.×1 0 ¯1 ⍝ Vector inner (dot) product Multi-dimensional array reduction (where the reduce construct was first named as such) +⌿2 4 6 ⍝ Sum of a list APL is a language which overcomes the inconsistencies (and difficulty in typing / parsing / executing) traditional mathematical notation by unifying certain constructs, such as:
