     Have you noticed that there are several similarities with math and science?  I bet you have.   Well, there are some that I would like to point out.  One similar thing is that you use a lot of math on science.  For example, you have to add and subtract things so you can get your answer in science.
     Some other examples are that you have similar objectives or things to figure out in science as you do in math.  You use a lot of math in science actually.  There are several things that are simple like decimals and rounding etc. that you use in science, but you learned in math.  All in all, there are several things in science that you use, but you learned them in math.

     What are negative numbers?  Where do you find them?  How do you use them in real life?  These are all some questions that you might ask about negative numbers, and I am going to try to answer them for you.
     You can find negative numbers anywhere in math, I mean we should all know at least that much.  They are also found in real life situations such as banking deposits, debt, etc.  So, basically, they are found in money.  You might see a negative number where you are looking at a bill of some sort.  For example, when you spend money with a credit or debit card, it will show a negative number which is the price you paid i.e.- you paid $20 for a shirt, it would show up as -$20  showing that you paid that amount.  They are also found in temperature such as below 0 degrees i.e. - it is -15 degrees outside todayAll in all, negative numbers are used everywhere and everyday.

     Today I am going to explain step by step how to solve the equation 2x-7=15.  Here we go:
2x-7=15
Step 1:  add 7 to both sides.
Why?  You add 7 to both sides in order to get x alone.  You will end up with 2x=22.
Step 2:  divide by 2.
Why?  Right now you have the quantity of 2x.  In order to get the amount of x, you must divide by 2.  This will leave you with x=11.  Now you are done.  Your answer is x=11.
