The Calculator app on your iPhone may seem boring and basic, but there are a few interesting tricks worth knowing. You can ask Siri to perform calculations for you, long-press on results to copy them, long-press the field to paste numbers in, and swipe left or right above the keypad to delete digits one by one. The app can also be used as a scientific calculator with just a simple maneuver.
Willpower is a pretty significant word. It's the difference between sticking with a clean eating diet and diving face-first into a plate of brownies. It's what drags you out of bed on Monday mornings and into work rather than letting you stay snuggled under the covers asleep. And, most importantly, it's the kick in the butt we all require to both accomplish goals and make changes.

In this video we will learn about algebra SCIENTIFIC NOTATION and STANDARD FORM. Watch the above math video to learn how to change large numbers from standard form to scientific notation.
Learn how to convert from scientific notation to standard form by watching the above math video. To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates. Do not write the power of ten anymore.
