Somewhere near the toilet, there should be a shut-off valve. It's generally a small knob found on the wall or floor near the toilet. This shuts off the water supply when turned clockwise, allowing the toilet to drain. Be careful not to break the valve or the pipe. Hold the base of the valve with one hand and turn it with the other. Carefully take the top off of the toilet tank and set it aside on a soft surface, like a towel, so it doesn’t break. This way, you can see the water as it drains to make sure it's draining completely. Press down on the flush valve. Flushing the toilet should cause the water in the tank to start to drain. If the water doesn't appear to be draining, double check the shut off valve. Make sure you twisted it as far as you can to switch off the water supply. If the toilet knob will not shut off properly, try temporarily shutting off the water supply to your house. Keep pressing down on the flush valve. Hold it down until all the water drains from the tank of your toilet.

One-sentence summary -- Turn off the water supply to the toilet. Remove the top of the tank. Flush the toilet. Hold down the valve until all the water has drained.

Q: The Euclidean algorithm is a system of repeated divisions, using the remainder each time as the divisor of a new division. The last divisor that divides evenly is the greatest common factor (GCF) of the two numbers. For example, the following steps illustrate the Euclidean algorithm being used to find the GCF of 272 and 36:   272=7∗36+20{\displaystyle 272=7*36+20}....divide the larger number (272) by the smaller (36) and note the remainder (20)  36=1∗20+16{\displaystyle 36=1*20+16}....divide the previous divisor (36) by the previous remainder (20). Note the new remainder (16).  20=1∗16+4{\displaystyle 20=1*16+4}....Repeat. Divide the previous divisor (20) by the previous remainder (16). Note the new remainder (4).  16=4∗4+0{\displaystyle 16=4*4+0}....Repeat. Divide the previous divisor (16) by the previous remainder (4). Since the remainder is now 0, conclude that 4 is the GCF of the original two numbers 272 and 36. With your linear equation in standard form, identify the coefficients A and B. Apply the Euclidean algorithm to find their GCF. Suppose you need to find integral solutions for the linear equation 87x−64y=3{\displaystyle 87x-64y=3}. The steps of the Euclidean algorithm for the coefficients 87 and 64 are as follows:  87=1∗64+23{\displaystyle 87=1*64+23} 64=2∗23+18{\displaystyle 64=2*23+18} 23=1∗18+5{\displaystyle 23=1*18+5} 18=3∗5+3{\displaystyle 18=3*5+3} 5=1∗3+2{\displaystyle 5=1*3+2} 3=1∗2+1{\displaystyle 3=1*2+1} 2=2∗1+0{\displaystyle 2=2*1+0} Because the Euclidean algorithm for this pair continues all the way down to dividing by 1, the GCF between 87 and 64 is 1. This is another way of saying that 87 and 64 are relatively prime. When you complete the Euclidean algorithm to find the GCF of A{\displaystyle A} and B{\displaystyle B}, you need to compare that result with the number C{\displaystyle C} of the original equation. If the greatest common factor of A{\displaystyle A} and B{\displaystyle B} is a number that can divide into C{\displaystyle C}, then your linear equation will have an integral solution. If not, then there will be no solution.  For example, the sample problem 87x−64y=3{\displaystyle 87x-64y=3} will have an integral solution, since the GCF of 1 can be evenly divided into 3. Suppose, for example, that the GCF had worked out to be 5. The divisor 5 cannot go evenly into 3. In that case, the equation would have no integral solutions. As you will see below, if an equation has one integral solution, then it also has infinitely many integral solutions.
A: Review the Euclidean algorithm. Apply the Euclidean algorithm to the coefficients A and B. Identify the greatest common factor (GCF). Interpret the result.

Article: If you wish to block a number from sending you voice calls, open the phone app.  If you wish to block a number from sending you text messages, open the text message app. It the Phone app, you can usually find a list of calls in the "Recent" list.  Recent text messages are displayed when you open the Text message app. It's the button with three dots in the upper-right corner of the call or text message.  This displays a drop-down menu. It's in the drop-down menu when you tap the icon with three dots in the upper-right corner. This blocks the number from your Android device.  Numbers blocked from the Phone app go straight to voicemail.  Numbers blocked from the Text app go to a separate folder.  If you do not want to receive voicemail or text messages from a number, use Methods 1 and 2 to block a number from your Sprint account.  Numbers blocked from your Sprint account are informed that you are not receiving calls when they try to contact you. To learn how to block a voice calls on iPhone, read How to Block a Number on iPhone.
Question: What is a summary of what this article is about?
Open the Phone or Text app. Open a call or text message from the number you want to block. Tap ⋮. Tap People Options (text messages only). Tap Block Number.
