Remove 'In' and 'pp' from bibliography

Question

I want to remove the 'In' an 'pp' that is produced in the bibliography. These are some of the commands in the preamble:

\documentclass[11pt,a4paper,oneside,]{memoir}
\usepackage[utf8]{inputenc}
usepackage{amsfonts}
\usepackage[left=3.50cm, right=3.0cm, top=3.0cm, bottom=3.0cm]{geometry}
\usepackage{graphicx}
\usepackage[style=numeric, backend=biber]{biblatex}
\addbibresource{bibtest.bib}
\DeclareNameAlias{default}{last-first}
\usepackage{stmaryrd}
\usepackage{enumitem}
\usepackage{amsmath}

Answer 1

Use

\DeclareFieldFormat{pages}{#1}

to get rid of the 'pp.' in the bibliography for all types. If you only want that for journal articles, use \DeclareFieldFormat[article]{pages}{#1}.

For the 'in:', have a look at Suppress "In:" biblatex. The following removes the 'in:' only for @article

\renewbibmacro{in:}{%
  \ifentrytype{article}
    {}
    {\bibstring{in}%
     \printunit{\intitlepunct}}}

edit: Updated for biblatex 3.15's definition of in:.
