Alexandra has 78 emails in her box. she deletes 47 emails. how many emails are left in her box? draw jumps and label the number line to show your thinking.

i know the answer is 78-47=31 ( but i am having trouble with the jump labeling i know you can draw the line for the bar but can you just write the numbers in a row and i can line jump from there asap )

< > this is the jump and label to get the answer
