why do we need to know algebra

Mathematics is one of the first things you learn in life. Even as a baby you learn to count. Starting from that tiny age you will start to learn how to use building blocks how to count and then move on to drawing objects and figures. All of these things are important preparation to doing algebra. These are the years of small beginnings until the day comes that you have to be able to do something as intricate as algebra. Algebra is the key that will unlock the door before you. Having the ability to do algebra will help you excel into the field that you want to specialize in. We live in a world where only the best succeed. Having the ability and knowledge to do algebra will determine whether you will take the short cut or the detour in the road of life. In other words, ample

 why is a negative multiplied by a negative a positive

why is a negative multiplied by a negative a positive

It's best to think, perhaps, of the negative sign as a "change in direction". The default direction is to the positive end of the number line (to the right). So $3times 2$ moves us six units to the right, to land at $6$. $-3times 2$ changes direction and moves us $6$ units to the left of zero, to land at $-6$. $-3 times -2 = -(-3 times 2)$ reverses our direction once again, taking us back to the right six units from zero, the opposite direction than does $-3 times 2$ in the amount of $6$ units to the right. So in the end, we are at the "same position" whether we use $3times 2$ or $-3times -2$. Note that our use of arithmetic, in a practical sense, depends on the context in which we are applying it. So your example is just a poor context to apply multiplication of negative numbers, since,

 why is there so much salt in the dead sea

why is there so much salt in the dead sea

Asked by: Marty O'Neill, by email The Dead Sea has a salinity of 33. 7 per cent. This is almost 10 times saltier than ordinary seawater. If you evaporated a litre of Dead Sea water, youвd have around 250g of salt left behind, and in the whole of the Dead Sea there are about 37 billion tonnes of the stuff. Ordinary sea salt is 97 per cent sodium chloride whereas Dead Sea salt is a mixture of lots of different chloride and bromide salts. Ordinary sodium chloride only makes up about 30 per cent. Thatвs still enough to supply the entire population of the UK with cooking salt for 70 thousand years! The, also known as the Salt Sea, is a salt lake bordering Jordan to the east and Israel and the West Bank to the west. It s a hypersaline lake that is truly one of Earth s unique places. Below you

 why do we need to stay healthy

why do we need to stay healthy

In addition to the three macronutrients, your body needs a variety of vitamins and minerals, too. Each vitamin and mineral plays a different role in your body; for example, vitamin D helps your body absorb the mineral calcium to create strong bones, while the mineral iron helps form hemoglobin in the blood. Other important vitamins and minerals include -- but are not limited to -- folate, magnesium, selenium, zinc and vitamins A, D, E, K and B complex. Although taking a multivitamin daily can help boost your health, the CDC recommends getting the vitamins and minerals you need from eating a balanced diet. Additionally, to avoid high blood pressure and other potential diseases, decrease the amount of sodium you eat; this is most easily done by preparing meals at home and choosing fresh

why do people believe the holocaust never happened

Only one-third of the world believes 6 million Jews died in the Holocaust. Monday was Holocaust Remembrance Day in Israel. Every year on this day, Israelis observe a two-minute moment of silence to pay tribute to the six million Jews killed by the Nazis during World WarбII. Here at dose, we OMGFacts. com Though many of the comments were respectful of the pain and suffering the Jewish people endured during World War II, there were a few too many people who seemed to deny that the Holocaust happened. Б6 million didnБt die it was all a lie,Б. БThe holocaust started because of zionist Jews and the NWO [New World Order],Б. БAhh yes, we must remember the time period in which Germany chemically treated the clothing of prisoners in labor camps with pesticides to stop the spread of typhus, which

 why do some objects sink while others float

why do some objects sink while others float

Students are given a plastic tub filled with a variety of materialsвwood of different sizes and shapes, a pencil, a marble, a styrofoam ball, a cork, a plastic spoon, a rubber band, a penny, a toothpick, a paper clip, and whatever else is handy. They are asked to predict which objects will float and which will sink when placed under the level of the water and let go. Students perform the experiment and compare the results to their predictions. They discuss why they thought certain objects would sink/float. The class brainstorms a list of properties of the different objects that may affect whether the object floats or sinks. Using the objects they already have, students do simple tests to rule out some of the properties (such as color, shape, etc). ...

 why do you want to work in asset management

why do you want to work in asset management

The Gateway spoke toВan employee of a London asset management firm with over 25 years' experience in the industry. What makes working in asset management special? There are three things that make this job special. Firstly, we're at the epicentre of global events; from politics to extreme weather, anything that affects markets and their behaviour is relevant to our work. And no two days are the same because every day something's happening which influences the way people invest. The second thing I'd highlight is that you get to interact with very interesting people. I've spent much of my career working in the UK stock markets, which means I've met, and in some cases formed professional relationships with, the chief executives of most of the leading companies in this country. The third thing

 why do the new pokemon look so stupid

why do the new pokemon look so stupid

They've even started dumbbing down the combat to the point where the game tells you what is super effective during battle. It plays the game for you and I don't understand that. You and me both know the type chart by heart, so how does this affect us? The game tells you what's effective, so what? It helps new players/players who don't have very good memory/players who don't understand the type chart. It does not in the slightest change the experience of us veterans. (Plus, you have to knockout the Pokemon before the game tells you what's effective against it - so even new players aren't given a huge advantage). Sorry if I'm being picky or singling you out, but the game telling you type effectiveness in battle is one of the changes I think is objectively an improvement and I'm just not

 why is water important in the body

why is water important in the body

What do you, the trees, and a hamster have in common? Give up? You all need water. All living things must have water to survive, whether they get it from a water fountain, a rain cloud, or a little bottle attached to the side of a hamster cage. Without water, your body would stop working properly. Water makes up more than half of your body weight, and a person can't survive for more than a few days without it. Why? Your body has lots of important jobs and it needs water to do many of them. For instance, your, which contains a lot of water, carries oxygen to all the cells of your body. Without oxygen, those tiny cells would die and your body would stop working. Water is also in lymph (say: limf), a fluid that is part of your, which helps you fight off illness. You need water to digest your
