Add the negatives.<br><br><br><br> +4 - 3 - 4 + 2 - 1<br><br> I just dont get it
vfiekz [6]

Answer: -2

Step-by-step explanation:

since there are no multiplication you can simply go from left to right doing simple math. You start from a +4 that would be a positive 4, you subtract -3 so you get +1 then you subtract -4 and the result is -3 (negative 3) so now you are currently working with numbers lower than 0, adding +2 will make it -1 and finally you subtract for -1 and that will make it -2. Hope it's what u needed
