plus.addEventListener("click",()=>numbers.textContent+="+");
minus.addEventListener("click",()=>numbers.textContent+="-");
multiply.addEventListener("click",()=>numbers.textContent+="×");
division.addEventListener("click",()=>numbers.textContent+="÷");

231,275 PointsRemember that "textContent" is always taken verbatim. What you're adding is HTML code. So do this instead:
plus.addEventListener("click", () => (numbers.innerHTML += "+"));
minus.addEventListener("click", () => (numbers.innerHTML += "−"));
multiply.addEventListener("click", () => (numbers.innerHTML += "×"));
division.addEventListener("click", () => (numbers.innerHTML += "÷"));
Also:
- the entity codes always begin with "&" and end with ";"
- + and − typically look nicer (and match the others better) than ordinary "+" and "-"
- ÷ is also a named entity code
And finally, another approach would be to just use the unicode characters directly as the textContent:
plus.addEventListener("click", () => (numbers.textContent += "+"));
minus.addEventListener("click", () => (numbers.textContent += "−"));
multiply.addEventListener("click", () => (numbers.textContent += "×"));
division.addEventListener("click", () => (numbers.textContent += "÷"));
