# How to make slash going through two digits?

I want to try make it slash both of 2 digits.

For example if I do $$\not{7}$$ it will slash that 7.

What to do for $10$ or bigger numbers?

Edit: $\require{cancel} \bcancel{10}$

• @mohamadmunzir mathjax is not used only by stackexchange, when using the commend "\cancel{ }" normally you would have to add "\require{cancel}" before. but in stackexchange, the site do it for you so you dont need that line – Holo Nov 6 '17 at 21:41
