I know that there are some shortcuts to make math operations. For example(adsbygoogle = window.adsbygoogle || []).push({});

When you multiply 11 and another number (23 for exaple) you just write those two numbers like this:

2 3

and then sum them "2+3=5" and the result you write it in the middle:

2 5 3

and that's it.

Can you help me and write those kind of shortcuts, it would really help, thanx
