If you move it to the numerator, its exponent also becomes positive. There are also rules for calculating with negative numbers. The same actually works for negative exponents on the bottom. But if anexpression is complicated then it may not be clear which partof it should be evaluated rst, andso some rules must be established. Find the number that you can mulitply with 5 to create 0. mc-TY-rules-2009-1 Evaluating expressions involving numbers is one of the basic tasks in arithmetic. Now, follow the same approach with 0 / 5. How can you figure this out? You can divide the entire amount (let's say, $76.02) by the amount shown on your receipt (say, $12.67), which is the amount of one charge. In the video above we subtracted using Algebra tile, another way to thing about subtracting integers is by using a number line. Multiplication and division (positive) × (positive) positive (negative) × (negative) positive (positive) × (negative) negative (negative) × (positive). If you were solving 8 / 2, you would find the number that you can multiply by 2 to create the 8. You want to confirm the number of over-charges before you call your bank to correct the situation. Some portion of that total debit (being a negative on your account) is wrong. You can tell from the amount that, yes, he actually charged you way more than once. When you get home, you check your bank account online. He swipes it six times before finally returning the card to you. When you go to pay, the kid has trouble running your debit card. But in what context could dividing a negative by a negative (and getting a positive) make any sense? In this context, getting a negative answer makes sense. Positive + Positive Positive A positive integer plus another positive integer will always produce a positive answer. So, for instance, if you owe $10 to six people, your total debt would be 6 × $10 = $60. Some people like to think of negative numbers in terms of debts.
