# Can bold characters be embedded within maths text, for use with vectors and matrices etc?

Aug 4, 2017

Yes.

#### Explanation:

The idea here is that you can get the bold text within math texts by using two functions, mathbf() or bb().

For example, you can write things like

• without hashtags

mathbf(ax^2 + bx + c = 0)

• with hashtags

$m a t h b f \left(a {x}^{2} + b x + c = 0\right)$

Alternatively, you can have

• without hashtags

bb(ax^2 + bx + c = 0)

• with hashtags

$\boldsymbol{a {x}^{2} + b x + c = 0}$

So you can use these functions to add bold text to your math formatting.

• without hashtags

{: (bb(0), bb(0), bb(0), bb(0)),(1, 1, 1, 1), (color(red)(2), color(red)(2), color(red)(2), color(red)(2)), (3, 3, 3, 3), (4, 4, 4, 4) :}

• with hashtags

$\left.\begin{matrix}\boldsymbol{0} & \boldsymbol{0} & \boldsymbol{0} & \boldsymbol{0} \\ 1 & 1 & 1 & 1 \\ \textcolor{red}{2} & \textcolor{red}{2} & \textcolor{red}{2} & \textcolor{red}{2} \\ 3 & 3 & 3 & 3 \\ 4 & 4 & 4 & 4\end{matrix}\right.$
