$${\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}} = {\mathtt{7}}$$

how is that possible when:

$${\mathtt{7}}{\mathtt{\,-\,}}{\mathtt{4}} = {\mathtt{3}}$$

yet

$${\mathtt{78}}{\mathtt{\,\times\,}}{\mathtt{376}} = {\mathtt{29\,328}}$$

I don't see how the last equation relates to the other two, but the other ones can be pretty easy take this for example

10+3=13

3-13=10

It acually quite basic, I don't know a better way to explain it
