Todays blog will be about the similarities of Science and Math.These two subjects are very alike, because you need Math to help solve the hypothesis of Science. For example, how are you going to solve an equation when Math is not around? Math also needs Science , because how are we going to know what equations to use if we do not have science Science and Math also kind of go together. What ever you are learning in Math kind of connects with what you are learning in Science. A great term to combine these two is Geometry and Physics.
This is a very great deal, because the two subjects can not function without each other. It is almost like they are a couple. If you really think about it, they have a lot of simularities. They both have an equation and a question to follow. The equation for Science may if you add 1/2 cup of foaming powder to a cup of water how many cups of foaming powder do you need for 173 cups? I hope that you understand how much Math is needed in Science. Until next Math Monday blog!
Todays blog is going to be about negative numbers. Negative numbers are numbers on the left side of a number line. Some people say that they are real negative numbers on the number line. In other words some say that you own -5 dollars to that person instead of owing 5 dollars. This is wrong because you don't owe -5 dollars there is not a -5 dollar bill in the world. People don't say this because it sounds weird. Negative number are mainly used in math. For example the most common way of using them is for a math problem. For example, -5+2. The negative always stays negative. To solve this problem you would need to use a number line with negative and positive numbers.
I hope that you understand the difference with using negative numbers on a number line and how to say it. This can be tricky, but it will work out in the end. Just remember you don't owe -5 dollars, you just owe 5. It is better to know what how much you owe someone. I remember learning this in fifth grade. I really like this lesson, because it is very easy to understand. This topic is like the topic integers. It is basically the same thing. I also hope that you know what intergers are! Until next Math Mondays blog!
In Todays blog, I will be explaining how to solve 2x-7=15. The first step is to isolate the variable By that I mean to add 7 into 15. This would add up to 22. If you are asking why you have to add, well this is because if the sign right next to the variable is positive than you subtract, however if it is negative than you add. Once the first step is done all you have left is 2x=22. From this point, it is really easy. All you need to do is divide 2 by 22. The answer is 11. The same thing goes with the +/- deal. If the sign is multiplication then you divide and the other way around. This is simply all you have to do for a problem like this one.
I hope that you have learned a lot about my blog, and that you will refer back to this when you have a problem like this. Just remember that multiplication and division rule. It is fairly simple if you show your work and follow these steps. If you do not know or forget which step to do first follow the GEMS rule. GEMS stands for grouping exponents multiplication/division, and subtraction/addition. This is what we learned awhile back in 5th grade, so this should be easy.
