How do I align the equal signs for working out I have in latex?

With the intergral $\displaystyle \int$ how do I put number at the top and bottom? And how do i also do this for the large brackets $\displaystyle [...]$ ?

\int_{a}^{b}f(x)dx = F(x) \bigg|_{a}^{b}=F(b)-F(a)

$\displaystyle \int_{a}^{b}f(x)dx= F(x) \bigg|_{a}^{b}=F(b)-F(a)$

Large brackets

\left[ \left( \frac{1}{2}\right) \right]

$\displaystyle \left[ \left(\frac{1}{2} \right) \right]$

3. so is it possible to align equal signs?

also is there a keybord shortcut to putting the wrap on a highlighted text? (sort of like how ctrl+b to embolden the selected text) 4. Originally Posted by foreg0ne How do I align the equal signs for working out I have in latex?? Use the \begin{aligned}...\end{aligned} tags. I.e. [tex]\begin{aligned}\int_0^1x^2\,dx & = \left.\left[\frac{x^3}{3}\right]\right|_0^1\\ & = \frac{(1)^3}{3}-\frac{(0)^3}{3}\\ & = \frac{1}{3}\end{aligned} give you

\displaystyle \begin{aligned}\int_0^1x^2\,dx & = \left.\left[\frac{x^3}{3}\right]\right|_0^1\\ & = \frac{(1)^3}{3}-\frac{(0)^3}{3}\\ & = \frac{1}{3}\end{aligned}

Not a keyboard shortcut, but in the menu bar above the panel where you input text there is a $\displaystyle \Sigma$ symbol. Click on that to wrap [tex] around highlighted text.
