i am using nuxt 2.8.1

i have 100 inputs. All inputs are number

i want to calculate in sum all number to get total

i tried this

```
computed: {
total() {
return this.form.one + this.form.two
}
}
```

# what i expected

5 + 5 = 10

# what output getting

5 + 5 = 55

if i don’t put value in two

result `5null`

i don’t understand why its

It considers them like strings and concatenates them like you see, so you should use a `Number`

object to cast them to integers like :

```
return Number(this.form.one) + Number(this.form.two)
```

to be more efficient i recommend to use `reduce`

function since you’re having multiple inputs :

```
return Object.values(this.form).reduce((a,c)=>{
return a+Number(c);
},0)
```

Example :

```
let form = {
one: 45,
two: 5,
three: 7
}
let sum = Object.values(form).reduce((a, c) => {
return a + Number(c);
}, 0)
console.log(sum)
```

###

Since your param is a form, i guess this is related to user input. Then you could also solve it with a modifier (https://vuejs.org/v2/guide/forms.html#number)

HTML

```
<input v-model.number="form.one" ></input>
<input v-model.number="form.two" ></input>
```

JS (same as it was before, or with the reduce method)

```
computed: {
total() {
return this.form.one + this.form.two
}
}
```
