Did you know that dividing numbers can often feel like magic? When you divide a negative by a negative, like in your expression, the result turns positive! So, when you simplify , you first multiply 70 by -6 to get -420. Dividing -420 by -14 gives you 30, which is as cheerful as a sunny day!

Speaking of real-world applications, understanding how to simplify expressions like this can boost your math skills, especially in budgeting! For instance, if you were trying to figure out how much money each person owes after a group dinner that cost a certain amount, knowing how to divide negative and positive numbers correctly can help you avoid budget blunders!
