Problem 1:
The temperature in one winter morning in Edinburgh was -6°C. By 2 PM, the temperature had increased by 5 degrees. What was the temperature by 2 PM?
Answer:
Refer to the first number line. You would start counting five units to the right from -6. You would stop at -1 and that is the answer to the question
Problem 2:
Anna had $4 balance in her bank account. She used her debit card to purchase a meal deal that costs $5. Her bank account allows overdraft. What amount would her bank statement shows if Anna had not deposit any money since her last purchase?
Answer: Over draft means that a bank allows their customer to make purchase more than what they've got left in their balance but this means the customer will be in debt to the bank. Anna had $4 in the bank and she made a purchase of $5. Her bank statement would show
4 - 5 = -1
Using the number line, you would start from 4 and count back 5 to get to -1
