Having trouble with datalist and redirect of results

Hello I am trying to make a redirect of search results from my search bars but it returns all the search results to the very last statement I make in the function

HTML

   <input type="text" class="educationSearchBar" id="calculatorSearch" placeholder="Type an Equation Name or the equation" list="educationList">
      <div id="educationListOutput"></div>

JS to show the datalist

    var industries = '<datalist id="educationList"> \
    <option value="Algebra"></option> \
    <option value="Analytical Chemistry"></option> \
    <option value="Chemistry"></option> \
    <option value="Economics"></option> \
    <option value="Financial Acounting"></option> \
    <option value="Geometry"></option> \
    <option value="Managerial Accounting"></option> \
    <option value="Organic Chemistry"></option> \
    <option value="Physics"></option> \
    <option value="Precalculus"></option> \
  </datalist>'; 

    var educationList = document.querySelector('#educationListOutput');

    educationList.innerHTML = industries;

here is the JS for the search redirection

              var inputSearchCalc = document.querySelector('#calculatorSearch').value;
        var searchCalcBtn = document.querySelector('#search-calculator-index');

        function searchCalc() {
            if (inputSearchCalc = 'Algebra') {
                window.location = '/educationSec/calculatorSubjects/algebra/algebra.html'
            } 
            if (inputSearchCalc = 'Analytical Chemistry') {
                window.location = '/educationSec/calculatorSubjects/AChem/AChem.html'
            } 
            if (inputSearchCalc ='Chemistry') {
                window.location = '/educationSec/calculatorSubjects/chemistry/chemistry.html'
            } 
            if (inputSearchCalc = 'Economics') {
                window.location = '/educationSec/calculatorSubjects/economics/economics.html'
            }
            if (inputSearchCalc = 'Financial Accounting') {
                window.location = '/educationSec/calculatorSubjects/finAccounting/finAccounting.html'
            }
            if (inputSearchCalc = 'Geometry') {
                window.location = '/educationSec/calculatorSubjects/geometery/geometery.html'
            }
            if (inputSearchCalc = 'Managerial Accounting') {
                window.location = '/educationSec/calculatorSubjects/manAccounting/manAccounting.html'
            }
            if (inputSearchCalc = 'Organic Chemistry') {
                window.location = '/educationSec/calculatorSubjects/organicChem/organicChem.html'
            }
            if (inputSearchCalc = 'Physics') {
                window.location = '/educationSec/calculatorSubjects/physics/physics.html'
            }
            if (inputSearchCalc = 'Precalculus') {
                window.location = '/educationSec/calculatorSubjects/precalc/precalc.html'
            } 
        }

     searchCalcBtn.addEventListener('click' , searchCalc);

All of the results redirect to the precalc page which is the last one
