 ### The Modulus of a vector
 The modulus of a vector is a positive scalar number that gives magnitude of the vector. It is written like this:
 
-<span class="texhtml">|<strong>AB</strong>|</span> or <span class="texhtml">|<strong>a</strong>|</span> or simply <span class="texhtml"><strong>AB</strong></span> or <span class="texhtml"><strong>a</strong></span>.
