A post of a partial solution raised some questions that start in the while loop after the if statement. The if statement makes all a values odd. Outside of it a values are not always odd once they are mixed with b values.

In the outside loop why do the values start at what seems like the second run?

```
console.log(temp,a,b); //1,2,1 not 0,1,0
```

```
function sumFibs(num) {
let total = 0;
let a = 1;
let b = 0;
let temp;
while (total <= num) {
if ( a % 2 !== 0 ) {
total += a;
}
temp = a;
a += b;
b = temp;
}
return total;
}
sumFibs(75024);
```
