Your requirements could not be resolved to an installable set of packages.

Problem 1
- moontoast/math 1.1.2 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
- moontoast/math 1.1.1 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
- moontoast/math 1.1.0 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.
- Installation request for moontoast/math ^1.1 -> satisfiable by moontoast/math[1.1.0, 1.1.1, 1.1.2].

To enable extensions, verify that they are enabled in your .ini files:
- /usr/local/etc/php/php-cli.ini
- /usr/local/etc/php/conf.d/docker-php-ext-opcache.ini
- /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini
- /usr/local/etc/php/conf.d/docker-php-ext-zip.ini
You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.

As the message says, you need to enable the ext-bcmath PHP extension.
