PHP Extension bcmath is missing in PHP Extensions Check

Question

I found a lot of questions on this topic. but sorry, nothing can resolve my issue.

I am using virtual box to run centos 7. I have downloaded Magento 2.3. I tried composer install on my Magento folder and it returns the error,

moontoast/math 1.1.2 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system

so I searched for this error, and I got an answer to install bcmath with the command

sudo yum install php7.2-bcmath

at this time, I faced another issue, like error

and again searched for this and got another answer to try out with

sudo yum install php7.2-bcmath --disablerepo=epel\*

I ran this command, and the result shows like below,

enter image description here

and the thing is that I am just trying to configure Magento. I spent 3 days on it. really fed up. I got stuck.

Please help me to go forward. still, I am facing the issue with

moontoast/math 1.1.2 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system

my php -v is
