More fractions:
Warning: When you type a number and then a symbol and a fraction in this code, this fraction is overspaced, like described above. If you write it like this, that won't change. The first one is the only one that's the fixed fraction.
^3/_7 \to ^3/_7 • ^3\text{/}_7 \to ^3\text{/}_7
\(^3/_7 \to ^3/_7 • ^3\text{/}_7 \to ^3\text{/}_7\)
To fix this, type \text{ } on the left side of each fraction that you type. You must also do it this way when writing equations:
^3/_7 \to\text{ }^3/_7 • \text{ }^3\text{/}_7\\
^3/_7 +\text{ }^1/_7=\text{ }^4/_7
\(^3/_7 • \text{ }^3\text{/}_7 \\ ^3/_7 +\text{ }^1/_7=\text{ }^4/_7\)
Empty Boxes and Spacing
\begin{align}...
2\frac{1}{2}&=\boxed{\phantom{00}}\\...
&=\phantom{0}\frac{5}{2}...
\end{align} • insert~space •.insert\phantom{0}phantom\phantom{0}space • \begin{split}
\int_\boxed{}^\boxed{}\boxed{\phantom{0}}~dx...
\end{split}..
Note: The left figure for fractions is spacing called "phantom". "Phantom" is ideal for making empty boxed equations. The center figures show on the left a space using a tilde, and on the right a "phantom space" using the following command. The figure on the right shows a blank integral; the smaller boxes don't need a "phantom space" as the bigger box needs one.
\(\begin{align} 2\frac{1}{2}&=\boxed{\phantom{00}}\\ &=\phantom{0}\frac{5}{2} \end{align} • insert~space • insert\phantom{0}phantom\phantom{0}space • \begin{split} \int_\boxed{}^\boxed{}\boxed{\phantom{0}}~dx \end{split}\)
Fixed Limits
\lim\limits_{x \to \infty} \exp(-x) = 0
Note: Type "/lim", then "/limits" to fix the underset.
\(\lim\limits_{x \to \infty} \exp(-x) = 0\)
