In one sentence, describe what the following article is about: You want the fence to be high enough for you to rest your hand at a comfortable height while riding. If you know which foot is your front foot for sports like skateboarding, surfing, and snowboarding, you will want the pedal in the 4 o'clock position to be on the side of your dominant foot, and the pedal in 10 o'clock position to be for your non-dominant foot. Squeeze the seat comfortably with your upper thighs. Keep your body and the unicycle facing forward and parallel to the fence. Note that this is the opposite movement than you would perform on a bicycle, which requires that you step on the pedal furthest away to gain forward momentum. It will take a lot of practice to get used to moving backward instead of forward when mounting a unicycle. Take your time and be patient. You will immediately have to pedal slightly to keep your balance. You want the wheel to rotate 1/4-turn backwards as soon as you mount the unicycle. Once you mount the unicycle, the pedals should be directly vertical. Lean slightly forward in order to maintain your balance. This can take several hours to several days depending on your abilities. Once you feel ready, you can learn to free mount by following the same steps above without the assistance of a fence or handrail. Instead, use your hands to hold on to the seat as you mount or use your arms to help you balance.
Summary: Find a low fence and place the unicycle parallel to the fence so that you can use it for support as you mount the unicycle. Position the pedals of the unicycle in a slightly offset, vertical position so that one pedal is in the 4 o'clock position and the other is in the 10 o'clock position, mirroring the hands of a clock. Tilt the unicycle toward you until the seat of the unicycle rests between your legs. Continue to squeeze the seat between your thighs and place both of your hands on the fence. Step on the pedal closest to you in the 4 o'clock position with your dominant foot. Give yourself a little push with your other foot and sit on the unicycle seat, placing your non-dominant foot on the pedal furthest away in the 10 o'clock position. Hold on to the handrail and begin to pedal very slowly at first. Practice mounting and pedaling while holding on to a fence until you feel comfortable balancing on your own.

In one sentence, describe what the following article is about: You are going to need a bucket that can hold a lot of water. However, you must also keep in mind the weight of the bucket when full. For example, a gallon of water weighs a bit over 8 pounds, which means a 5 gallon (18.9 L) bucket full of water would weigh in at 40+ pounds, if completely full. Pet stores selling aquarium supplies often sell inexpensive vacuum kits. These consist of about a 2 inch (5.1 cm) (or larger) diameter by 6 to 18 inch (15.2 to 45.7 cm) rigid plastic tube. This tube will be open at one end, with a 1⁄2 inch (1.3 cm) diameter opening at the other end. Included in this kit will also be a fairly long length of 1/2" clear, flexible tubing. The 1⁄2 inch (1.3 cm) flexible tubing should be of sufficient length to reach from the furthest point inside the tank, over the tank top and downward into the bucket. Connect the wide rigid tube to the 1⁄2 inch (1.3 cm) flexible tube (if not already connected). The object of weekly maintenance is to remove solid waste and change about 25% of the water in the tank. This siphon procedure will do both at the same time. Before placing your hands in the tank, be sure to thoroughly wash your hands with soap and warm water, and rinse well. Marine life and plants can react negatively to dirt, bacteria, and even soap.
Summary: Obtain a suitable bucket. Procure a vacuum kit. Connect the vacuum. Wash and rinse your hands well.

In one sentence, describe what the following article is about: By using the order of operations, any calculations in parentheses must be completed first. For example:d=(6−2)2+(4−1)2{\displaystyle d={\sqrt {(6-2)^{2}+(4-1)^{2}}}}d=(4)2+(3)2{\displaystyle d={\sqrt {(4)^{2}+(3)^{2}}}} The order of operations states that exponents should be addressed next. For example:d=(4)2+(3)2{\displaystyle d={\sqrt {(4)^{2}+(3)^{2}}}}d=16+9{\displaystyle d={\sqrt {16+9}}} You do this calculation as if you were working with whole numbers. For example:d=16+9{\displaystyle d={\sqrt {16+9}}}d=25{\displaystyle d={\sqrt {25}}} To reach your final answer, find the square root of the sum under the radical sign.  Since you are finding a square root, you may have to round your answer. Since you are working on a coordinate plane, your answer will be in generic “units,” not in centimeters, meters, or another metric unit. For example:d=25{\displaystyle d={\sqrt {25}}}d=5{\displaystyle d=5} units
Summary:
Calculate the subtraction in parentheses. Square the value in parentheses. Add the numbers under the radical sign. Solve for d{\displaystyle d}.
