Javascript – How to do multiple math questions at once

I’ve tried a lot of things but it can only do 1+1 or 1-1 etc.

This is my code any fix or code to make this happen? thanks.

This uses the split method so you input has to be 1+1 etc

var Equation = prompt("Equation? (Can only take 1 math equation for now.      Upcoming updates soon!)");
  if (Equation === null) {
    close();
  }
  if (Equation.includes("+") === true) {
    const mySumAddition = Equation.split("+").map(x => parseFloat(x, 10));
    var AOne = mySumAddition[0], ATwo = mySumAddition[1];
    var additionAwnser = AOne + ATwo;
    alert(additionAwnser);
    var CO = confirm("Equation Done, Goodbye!");
  }
  if (Equation.includes("-") === true) {
    const mySumSubtraction = Equation.split("-").map(x => parseFloat(x,         10));
    var SOne = mySumSubtraction[0], STwo = mySumSubtraction[1];
    var subtractionAwnser = SOne - STwo;
    alert(subtractionAwnser);
    var CO = confirm("Equation Done, Goodbye!");
  }
  if (Equation.includes("*") === true) {
    const mySumMultiply = Equation.split("*").map(x => parseFloat(x, 10));
    var MOne = mySumMultiply[0], MTwo = mySumMultiply[1];
    var multiplyAwnser = MOne * MTwo;
    alert(multiplyAwnser)
    var CO = confirm("Equation Done, Goodbye!");
  }
  if (Equation.includes("/") === true) {
    const mySumDevision = Equation.split("/").map(x => parseFloat(x, 10));
    var DOne = mySumDevision[0], DTwo = mySumDevision[1];
    var devisionAwnser = DOne / DTwo;
    alert(devisionAwnser);
    var CO = confirm("Equation Done, Goodbye!");
  }
  if (CO === true) {
    close();
  }
  if (CO === false) {
    close();
  }

    • In this code handle one question at a time. and closes once that equation has been processed. split the input into an array

      const equationArray = Equations.split(‘,’);

    • The input must be divided up into an array of equations. iterate the
      each equation in array using loop
      for(const Equation of equationArray) {
      // include your code inside loop
      }

    • Don’t equal into true in side the if condition, because if condition return true.

    If what you want is to do multiple math questions at once like this 5+6+7+8-6-1*5+1=16 , 5+6+7+8-6-1*(5+1)=14 , 5**5=3125 (Equal to 5*5*5*5*5=3125)then this code may work.

    Note: Sorry if you don’t understand what i say . i am not good English.

    var Equation = prompt("Equation? (Can only take 1 math equation for now.      Upcoming updates soon!)");

if (Equation === null) close();
if (Equation.match(/+|-|/|*/g)) {
  var Answer = eval(Equation);

  alert(Answer);
  console.log(Answer)
  var CO = confirm("Equation Done, Goodbye!");

}
if (CO === true) {
  close();
}
if (CO === false) {
  close();
}
