verified again by acting on 3:
D = λ ABC. [(AB) C)] 3 = λ ABC. [(3B) (3B) C )〕
= λ ABC. [(3B) (B (BC)] = λ ABC. [B (BC)] = 6.
In fact, the basic arithmetic operations of addition, multiplication, and power-up can be defined
A = λ fgxy. [(FX) (Gx) y 〕,
M = λ fgx. [F (Gx )〕,
P = λ FG. [FG 〕.
Readers may mind convincing themselves or others. We do have the following results:
(AM) n = m + n, (MM) n = m × N, (PM) n = Nm,
Here m is N, which is the two natural number functions of the deflection, and m

I am talking about namespaces and package management as follows:
PHP is a lightweight feature, and now adds namespaces and package management.
I hope you don't want to chew on it too much. from my big point of view, I didn't place the namespace and package management on Lavavel. besides, Lavavel won't be able to make PHP changes. Python, Node. javaScript and PHP feel that there is no comparability. after all, the design pur
The latest Photoshop is the same as the Sketch output-cutting function (generator), with 2x PSD output 3x Chettu can also. and Photoshop with Slicy output cut diagram is much faster than Sketch 3.
Sketch is quite good, but at present (v3.1) still have a lot of small problem, add to Chinese support not good enough, in the interface design still can't replace Photoshop completely.
On the subject of the question, first of all, a design manuscript can n

In short, Illustrator is used to create graphics that Photoshop uses to set styles and outputs.
Specifications
If you can control the icon size, then the icon style and line thickness should help the specification, because many icons must have a centerline. That is, if an icon has an even width, the width of the centerline cannot be an odd number. Similarly, if an icon has an odd width, the width of the line is not even.

It is meaningless to catch up with others in such an impetuous manner. Just like China, it is always learning from others and always wanting to surpass others, but it is still left behind by others.
