# Calculator Project - issues with equal button

Hi there: I was able to make the equal button work. I am currently trying to make the signs (+, -, *, /) act like a equal button, so if I press 1 then + then 1 then +, I get 2. I was able to do that too with, currently, addition and subtraction. However, at this point, the equal button is not properly working: it only adds, but it doesn’t subtract. I thought it was (it still might be) something to do with the conditionals in the equal button, but it seems that it’s something to do with the logic–i.e. how the `if` statements are arranged.

I’m going to post snippets of my code and and the link to my Github for the full code.

``````function addButton() {
symbol = '+'
if(a !== '' && symbol === '+') { // a is not empty, thus it is pushed into c. Then a is cleared and symbol is +
c.push(Number(a));
a = '';

console.log(symbol);

if(a === '' && symbol === '+') { // when equals clears a, a symbol is chosen so it can do a process with the "number on the screen"
totalAmount = c.reduce((total, amount) => total + amount);
clearArr();
c.push(totalAmount);
console.log(totalAmount);
console.log(symbol);
``````
``````function subtractButton() {
symbol = '-'
if(a !== '' && symbol === '-') { // a is not empty, thus it is pushed into c. Then a is cleared and symbol is -
c.push(Number(a));
a = '';
console.log(symbolSub);
console.log(symbol);

};

if(a === '' && symbol === '-') { // when equals clears a, a symbol is chosen so it can do a process with the "number on the screen"
console.log(symbol);
console.log(a);
totalAmount = c.reduce((total, amount) => total - amount);
clearArr();
c.push(totalAmount);
console.log(totalAmount);
console.log(symbol);
``````
``````function equalsButton() {
//console.log(symbol);
if((symbol !== '-' && a !== '' )) {
c.push(Number(a));
console.log(symbol);
totalAmount = c.reduce((total, amount) => total + amount);
clearArr();
c.push(totalAmount);
console.log(totalAmount);
}
if((symbol === '-' && a !== '')) {
c.push(Number(a));
console.log(symbol);
totalAmount = c.reduce((total, amount) => total - amount);
clearArr();
c.push(totalAmount);
console.log(totalAmount);
};
``````

Is the issue here with how I’ve set up the conditions to be met? Is it the logic or something else? Thanks for the help.
