INPUT ARTICLE: Article: You can strike the nose of your attacker if they are in front of you or behind you, but the movement you use will vary depending on your starting position. If your attacker is in front of you, you will need to move in a forward direction. If your attacker is behind you, you will need to attack as you turn to face them. When standing face-to-face with your attacker, open your hand and strike straight forward, hitting the base of the nose and shoving it back. Throw your weight into the attack in order to apply the most force. This move causes your attacker's head to snap back, pinching the nerves of the upper spinal column and, if done with enough force, causing the opponent to black out. If the attacker is behind you, bend and lift your arm so that your elbow points toward the attacker's face. Rotate your upper body enough to throw your elbow into the side of the attacker's nose. The center side of the nose, on either side, is another pressure point of the body. If you strike hard enough, you can cause the nose to break and the attacker to fall unconscious.

SUMMARY: Assess the best way to strike depending on your position. Strike with the heel of your palm from the front. Strike with your elbow if the attacker is behind you.

INPUT ARTICLE: Article: In order to create an Iron Pickaxe, you will need 3 Iron Ingots and 2 sticks. Diamonds are found in the lowest levels of worlds, so the journey will be a long one. You'll want to ensure that you have enough provisions to able to stay and mine for a good amount of time without dying of hunger. You'll be down in the deepest reaches of the Minecraft world, so you're sure to come across some hostile mobs. Make sure you have some good armor and a trusty sword before heading out. Be prepared!

SUMMARY: Craft an Iron Pickaxe (wood, stone or even gold pickaxes won't work) so you can receive diamonds when you mine Diamond ore. Gather some food. Bring some weapons.

INPUT ARTICLE: Article: . Mixed numbers are whole numbers with fractions. To make it easier to subtract, turn the whole numbers into fractions. This will mean that the numerator will be larger than the denominator. For example, 2 3/4 - 1 1/7 will become 11/4 - 8/7. Find the lowest common multiple of both denominators so you can make a like denominator for the fractions. For example, if you're doing 11/4 - 8/7, list all the multiples of 4 and 7 to find 28. Since the multiples of 4 include 4, 8, 12, 16, 20, 24, 28 and the multiples of 7 include 7, 14, 21, and 28, 28 is the lowest number they have in common. You'll need to make denominators become the lowest common multiple. To do this, multiply the entire fraction. For example, to make the denominator for 11/4 become 28, multiply the fraction by 7. The fraction will become 77/28. If you've changed the denominator for 1 of the fractions in your problem, you'll need to adjust the other fractions so their ratios are still equal to the original problem. For example, if you've adjusted 11/4 to become 77/28, multiply the 8/7 by 4 to get 32/28. The problem 11/4 - 8/7 becomes 77/28 - 32/28. If the denominators were the same to begin with or you've made equivalent fractions, you can now subtract the numerators. Write the answer and place it over the denominator. Remember not to subtract the denominator. For example, 77/28 - 32/28 = 45/28. You'll probably need to change the answer into a mixed number. Start by dividing the numerator by the denominator to get a whole number. Then write how many parts you have left. This number will be the numerator. Place the numerator over the same denominator. Reduce this fraction if you can. For example, 45/28 becomes 1 17/28 because 28 goes into 45 1 time and has 17 parts of 28 left over.

SUMMARY:
Change the mixed numbers into improper fractions Find a common denominator if necessary. Make equivalent fractions if you have to change the denominators. Adjust all of the fractions in the problem to make them equivalent. Subtract the numerators and keep the denominator the same. Simplify the answer.
