Use the examples below as "milestones" to help you estimate the size of a hexadecimal number. This will give you a more intuitive understanding of hexadecimal, and let you read hexadecimal numbers without laboriously converting to decimal every time. As you'll see, one advantage to hexadecimal is that the number of digits doesn't increase nearly as fast as it does in decimal:  Humans have A fingers, or 1416 if you count the toes too. (Remember, the subscript 16 means a number is written in base sixteen.) In a residential area, drive below 1916 miles per hour (or 2816 kilometers per hour). A typical highway driving speed is 3C mph (or 6416 kph). Water boils at D4 ºFahrenheit (6416 º Celsius). The median U.S. income is roughly C350 dollars a year. The population of the world is over 1A0,000,000. You can do hexadecimal addition problems without ever converting to another system. It does take some mental effort and practice to remember the new rules. Here are a few methods and tips:  Count up one by one, using hexadecimal digits. For instance to solve 7+5 in hex, count 7, 8, 9, A, B, C. Learn the addition tables. A much faster method is to memorize the hexadecimal addition tables, which you can practice with an online quiz. Once you know that A + 7 = 1116, you don't have to laboriously count it out any more. Carry the one when needed. If your addition gets you past F, you "carry the one" as you would in a normal addition problem. For example, A+5 = F, A+6 = 1016, A+7 = 1116, and so on. Similarly, 3A+6 = 4016, 3A+7 = 4116, etc. Just like regular multiplication, the best way to become competent at hexadecimal multiplication is to memorize the multiplication tables. Here's the hex "6 times table" as an example (all numbers are hexadecimal):  6 x 1 = 6 6 x 2 = C 6 x 3 = 12 6 x 4 = 18 6 x 5 = 1E 6 x 6 = 24 6 x 7 = 2A 6 x 8 = 30 6 x 9 = 36 6 x A = 3C 6 x B = 42 6 x C = 48 6 x D = 4E 6 x E = 54 6 x F = 5A

summary: Teach yourself to read hexadecimal intuitively. Learn hexadecimal addition. Learn hexadecimal multiplication.

Many countries issue resident visas or permits to individuals who are willing to invest in the country's economy, and those resident visas can make you eligible for citizenship after a few years. This can be an expensive route as the minimum investment amounts range from several hundred thousand dollars to several million dollars. For example, the United States requires an investment of $1 million (or $500,000 if you are investing in a high unemployment or rural area), and in return you receive a conditional permanent resident permit. This path to citizenship can take a long time, so research the amount of time that it will take you to become a citizen before you decide to invest. For example, the United States and Belgium grant citizenship after five years of holding a resident permit of this type. However, Malta (whose minimum investment requirement is EUR 1 million) grants citizenship after only 1 year. Some states that grant investor visas also require that you remain a resident in that state before you can become a citizen. However, not all countries have residency requirements. For example, Cyprus does not have a residency requirement but the United States does. Not all countries permit dual citizenship. You may be required to renounce your prior citizenship in order to acquire citizenship by investment. If that is the case, you cannot become a dual citizen in this way.

summary: Consider acquiring a second citizenship by investment. Find out how long it will take to become a citizen by investment. Check to see if there is a residency requirement. Check the citizenship laws of the country in which you are investing.

Diabetes is a disease in which your blood glucose (sugar) levels are too high (hyperglycemia) due to a lack of insulin or a tissue insensitivity to it. In general terms, type 1 diabetes is more serious because your body (pancreas) doesn't make any insulin, whereas with the type 2 variety your body doesn't make or use insulin efficiently..  Both forms can be fatal if not treated.  All type 1 diabetics need insulin shots on a daily basis, whereas a large proportion of type 2 diabetics can manage their condition with special diets, weight loss and exercise. Type 2 diabetes is much more common and is linked to obesity, which causes tissues of the body to be less sensitive to the effects of insulin — essentially ignoring its impact. Insulin can't be taken by mouth (orally) in order to lower blood glucose levels because stomach enzymes interfere with its action. People with type 2 diabetes tend to be overweight and develop their symptoms slowly, whereas type 1 diabetics experience symptoms quickly and they tend to be more severe. The most common symptoms of type 1 diabetes include: increased thirst, frequent urination, extreme hunger, unexplained weight loss, sweet smelling breath (due to ketone breakdown), severe fatigue, irritability, blurred vision, slow-healing sores and frequent infections.  Type 1 diabetes can develop at any age, although it usually appears during childhood or adolescence. Diabetic kids are usually very thin, gaunt and tired looking. Type 2 diabetes can develop at any age, although it's most common in people older than 40 who are obese. Without insulin treatment, diabetes can progress and lead to nerve damage (neuropathy), heart disease, kidney damage, blindness, numbness in limbs and various skin conditions. Having diabetes and needing to inject insulin on a daily basis is sometimes like walking on a tightrope. Injecting too much insulin can lead to hypoglycemia due to having too much glucose removed from your bloodstream. On the other hand, not injecting enough promotes hyperglycemia as too much glucose is left within the blood stream. Your doctor can estimate the amounts, but it depends on your dietary choices. As such, diabetics must monitor their own blood sugar levels and determine for themselves when to inject.  Symptoms of hypoglycemia include: excessive sweating, shakiness, weakness, hunger, dizziness, headaches, blurred vision, heart palpitations, irritability, slurred speech, drowsiness, confusion, fainting and seizures.  Skipping meals and exercising too much can also promote hypoglycemia. Hypoglycemia can be treated at home in most cases by consuming quickly absorbed carbohydrates, such as fruit juice, ripe berries, white bread with honey and/or glucose tablets.
summary: Distinguish between diabetes types. Recognize the symptoms of type 1 diabetes. Understand the risks of injecting insulin.
