If I write:

const a = 1;
const b = 1;
const c = 1;
const d = 1;

const t = a * b * (c + d) / 100;

then some rule wants to change to:

const t = (a * b * (c + d)) / 100;
//        ^               ^ unwanted parentheses

I don't want the extra parentheses, but I can't figure out if it is ESLint or Prettier that adds them. My .eslintrc added below:

{
  "root": true,
  "parser": "@typescript-eslint/parser",
  "parserOptions": {
    "project": ["./tsconfig.json"]
  },
  "plugins": ["@typescript-eslint", "prettier"],
  "extends": ["eslint:recommended", "plugin:@typescript-eslint/recommended", "prettier"],
  "rules": {
    "no-console": 1,
    "prettier/prettier": 2,
    "no-case-declarations": 0,
    "no-extra-parens": 2,
    "@typescript-eslint/no-extra-parens": 2
  },
  "env": {
    "browser": true,
    "node": true
  }
}

Update

Here is what happens when I hover without the parentheses.
