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 please help asap thanks)
< --------------------------------78--------> this is the jump and label to get the answer
