Hello, how are you?
In this post I talk about some basic commands to create basic operations such as sub and superscipts, roots and vectors.
Remember that you need to import the
amsmath
andamssymb
packages, here I give you a brief introduction of these packages
Operators

Basic Operations We can sum, substact, multiply and divide with
+
,
,\times
or\cdot
and\frac{a}{b}

Sub and Superscripts We create a superscript with
{a}^{b}
and a subscript with{a}_{b}
.
Roots We create a root with
\sqrt{a}
or\sqrt[a]{b}

Roots We create a root with

Over and Underbraces An overbrace with text is
\overbrace{x+y}^{text}
and an underbrace is\underbrace{a+b}_{text}

Vectors We create a vector with
\vec{a}
or\hat{a}
Let's create something with this
Produces
Wait! Do you remember that in this post I told you that there was a difference between inline and displayed formulas, well
Produces
Did you noticed the difference? If not, in the fraction
The inline formulas adapts the size of the operator to print it in the same line while displayed formulas expands the size of the operations showing its real size :)
This is all for today. Thanks for reading
