## imron07 3 years ago How to insert new line, please :D

1. ParthKohli

Use "\\".  1\\ 2 \\ 3 \\ 4  yields$1 \\ 2 \\ 3 \\ 4$

2. ParthKohli

Similarly, you may start a new $$\LaTeX$$ bracket again. So,  $1$$2$$3$$4$  yields$1$$2$$3$$4$

3. ParthKohli

Notice how \\ is much more convenient if you want to use lesser spacing between two lines. :)

Thank you @ParthKohli :)

5. ParthKohli

You're welcome :)

I was always disturbed by lengthy spacing between eqs before.

7. ParthKohli

Me too! Another tip for you.  Right: $x + 3 = 8$$\implies x = 8 - 3 = 5$  The above is better since this doesn't do a lot of spacing between two equations. Here's what you should do.  Wrong: $x + 3 = 8$ $\implies x = 8 - 3 = 5$

$$hi\\hello\\testing\\1\\2\\3$$

Let's compare the outputs of both 'right' and the 'wrong'. Right -$x + 3 = 8$$\implies x = 8 - 3 = 5$ Wrong -$x + 3 = 8$ $\implies x = 8 - 3 = 5$

10. ParthKohli

Another good way is the following:  x + 3 = 8 \\ \implies x = 8 - 3 = 5

Wow, thanks for the bonus tip. What about making equals aligned. Is there a way?

12. KingGeorge

To make equals aligned, it's a little bit weirder. There are two ways that stand out to me. 1: f(x)=4x+7(x+3) \\ f(x)=4x+7x+21 \\ f(x)=11x+21 which outputs$f(x)=4x+7(x+3) \\ f(x)=4x+7x+21 \\ f(x)=11x+21$The downside to this, is that you always have to have the same stuff before the equals sign. 2. \begin{aligned} f(x)=32 &=4x+7(x+3) \\ &=4x+7x+21 \\ &=11x+21 \\ 32-21&=11x \\ 11&=11x \\ x&=1 \end{aligned} which outputs \begin{aligned} f(x)=32 &=4x+7(x+3) \\ &=4x+7x+21 \\ &=11x+21 \\ 32-21&=11x \\ 11&=11x \\ x&=1 \end{aligned}You start with \begin{aligned} and end with \end{aligned}. To start a new line, you use \\ and wherever you put the & sign, that's where it lines things up. In this case, I put them in front of the equals signs. This method gives you much more flexibility, but it takes longer to type.

Yaay, thanks @KingGeorge !

14. KingGeorge

You're welcome.

15. ParthKohli

That's something new I learned; I've heard only of \begin{align} .

16. KingGeorge

Technically speaking, they're almost the same, but you should use "aligned" if you're working in a second environment. So if you have an equation environment, you need to use "aligned" to align your lines. In the standard math mode, I think "align" is technically more correct, but they have the same effect in math mode, so I just always use "aligned."
