Question

Will someone please help me?

Answer 1

So, you are going to start with the first # and move left however many digits the second number is; if they are both negative and you are adding, just act like you are adding two regular #s together, just put a negative sign in front

Answer 2

When you're adding 2 negatives, you see the first negative then you jump forward since you are adding but if you were subtracting then you would jump backwards just like if you were doing positive numbers if you were adding then go forward if subtracting then go back.
Hope this helped!
