Here are the three most important things that I believe you need to know before going into the (exponent) unit test!

1. How does the multiplication rule for negative numbers apply to powers with negative bases?
1. if it’s a negative base (in brackets) and an even power, the answer will we positive. If it’s a negative base (in brackets) and an odd power, the answer will be negative. if it’s an negative base (not in brackets) and either an even or odd power, the answer will always be negative. Here’s a small cheat sheet chart to help you!
1. (-base) ^even = positive
2. (-base) ^odd =negative
3. -base^even = negative
4. -base^odd = negative
2. LAWS
1. Product Law; when we multiply exponents with the same base, we ADD the exponents.
2. Quotient law; when dividing exponents with the same base, we SUBTRACT the exponents.
3. Power of a power law; When an exponent is raised to another exponent, we multiply the exponents.
3. Follow the orders of operations (BEDMAS) when evaluating expressions involving powers.
1. Brackets
2. Exponents
3. Divide & multiply in order from the left to the right
4. Add & subtract in order of left to right

1. Consider a problem that could be solved by an app.
1. a problem could be not wanting to study science because you might not be interested in what’s going on or you don’t know methods to studying.
2. Brain storm
1. when I am studying try to create mnemonic devices in my head or find a video on YouTube explaining what we’re learning in class. but sometimes it’s hard to just read out your notes and trying to memorize all the information.
3. Find an app
1.  I realized my best option would be to find an app that was simple but very helpful rather than one that took too much time to program to your specific standards. I looked up online some good studying apps and I found an app called Flashcards+ and I gave it a try.
4. Using the app
1. using the app at first, I really liked it. it has a lot of useful tools to use and help you study. It eliminates the hassle of wasting time and paper hand writing usually 20+ flashcards on individual pieces of paper and going back and forth looking at your notes trying to copy the information down.
5. Debrief
1. after I knew what kind of app I wanted I did some research on google and the App Store I found my app (Flashcards+) ad started using it. I didn’t get to use my technique of a mnemonic device to study but instead more or less memory techniques. I overall liked the app but wish it was a little more organized. I did appreciate that when you first get the app it has kind a how-to use the app mode.
