What are some connections between math and science? Math will always be a part of science. The question is, how are there or what are the connections between science and math. One way you know that math will always be a part of science because there are certain things you need equations to solve how old something is or how it was first formed.
     For example, the relative dating method is a way that you can find how old something is. In order to find how old it is, you have to use a special equation, just like the one in the relative dating method. There could also be another method for figuring out the speed of how rock change. For example, the four time periods. From before the dinosaurs live, to now.

What are negative numbers? Where do you find and use them in real life? Negative numbers are numbers that come before zero, and it could mean you owe something. Think about a bank account, if you have the money then you could take it out whenever you want. Then you decide to take out more money than you have, which takes you into the negatives. That means you now owe money to the bank.
     If you are trying to solve a math problem, you could easily find a lot of negative numbers there. For example, try solving an algebra equation, you could always find negatives there depending on the numbers. The negative sign is just like a minus sign. When you have a minus sign you subtract, but you could still stay in the positives. If you take more then you have then you will owe that.

Last Monday, I wrote about how you convert the fraction into a decimal, now it's the opposite. Converting a decimal into a fraction isn't any harder than converting a fraction into a decimal. If you have a decimal, for example, .3 you would easily be able to convert that because .3 is a tenth, and in the fraction it's three over ten. 
      Here is another example, except this one is using hundredths. So if you had .03 the answer in the fraction would be three over a hundredth. Each time you add a zero after the decimal, you add a zero to the denominator. That would mean if the decimal was .003, then when you add a zero then you would get the fraction of 3 over a thousandth.

How would you solve the problem above? In order to solve the problem you need to figure out what x is. You find x by getting 2x on one side. In order to get x on one side, you have to add 7. Whatever you do to one side you have to do to the other. So you add seven and your new equation is 2x=22. After that, you just have to divide 2 so you can get x by itself. So the answer would be 11, or x=11.
     That would be a method to use when you solving any kind of those types of problems. Wheather it has more than one x or not, it's pretty much the same thing. Here are the steps again: add seven so you can get x by itself, divide by two and get an answer of 11. The answer would only work for this problem, but the steps are pretty much the same.
