"Your system is missing the required PHP extension bcmath."

Say hello to the developers,

I'm trying to use Composer for my PHP project on a recently launched development server, but for some reason I'm unable to do so. I successfully installed Composer, however, when I try to run the require command, I get the following error:

root@webserver:/var/mypersonal/index# composer require php-amqplib/php-amqplib
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/php_openssl.dll' - /usr/lib/php/20151012/php_openssl.dll: cannot open shared object file: No such file or directory in Unknown on line 0
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Using version ^2.6 for php-amqplib/php-amqplib
./composer.json has been created
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - php-amqplib/php-amqplib v2.6.3 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
    - php-amqplib/php-amqplib v2.6.2 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
    - php-amqplib/php-amqplib v2.6.1 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
    - php-amqplib/php-amqplib v2.6.0 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
    - Installation request for php-amqplib/php-amqplib ^2.6 -> satisfiable by php-amqplib/php-amqplib[v2.6.0, v2.6.1, v2.6.2, v2.6.3].

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.0/cli/php.ini
    - /etc/php/7.0/cli/conf.d/10-mysqlnd.ini
    - /etc/php/7.0/cli/conf.d/10-opcache.ini
    - /etc/php/7.0/cli/conf.d/10-pdo.ini
    - /etc/php/7.0/cli/conf.d/20-calendar.ini
    - /etc/php/7.0/cli/conf.d/20-ctype.ini
    - /etc/php/7.0/cli/conf.d/20-exif.ini
    - /etc/php/7.0/cli/conf.d/20-fileinfo.ini

    - /etc/php/7.0/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.0/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.0/cli/conf.d/20-tokenizer.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, deleting ./composer.json.

I'm assuming this has something to do with the PHP warning I'm getting when running the composer require command, but no Google search results lead me in the right direction.

Additionally, I have provided my /etc/php/7.0/cli/php.ini file in case there are errors in that file.
