Hi, today I'm going to teach you how to turn off two calculators. Here, we have a standard big button eight-digit Staples-made calculator. You probably use this calculator or something similar to it in your home. And here, we have a small, compact, and portable calculator that you'd probably use for school. These calculators are pretty good; the only problem is that there's only one way to turn them on and no way to turn them off. So, the only way that they would turn off is by themselves. Here's how to turn them off: first, turn your calculator on. Then, hold five, six, or seven of the buttons and then press "on" again, and it should turn off. Again, just turn it on, hold six, seven, or eight of the buttons, and then press "on". The amount of buttons will depend on your calculator. It works on this one too; just hold a few of the buttons seven, eight, six, seven, or eight, or whatever, and then press "on". Your calculator should turn off again. Just hold six, seven, eight, or the buttons and then press "on", and it'll turn off. And it's that simple! Thanks for watching, and with this, you can save your calculator's battery life.
