Could I Have Dyscalculia?

We Answered:

I have never heard of "dyscalculia," but this sounds like a very specific learning disability. Because you have average/above-average abilities in other areas and have persistent difficulties despite what appears to be adequate teaching and time spent with the material, it is likely that there is some kind of processing problem interfering with your ability to perform numerical calculations.
The best thing to do at this point is to figure out ways to work around what is difficult for you and capitalize on your strengths. For the rest of your life you will be able to use a calculator when you need to do math, there is no shame in relying on a calculator for things like figuring out a tip or working out a budget. Figure out the areas you will need these skills for and what you can do instead to work around these problems.
Since you are still in HS it would be worthwhile to ask for an LD assessment. You could receive accommodations for your work in the algebra classes that might help you bring your grades up. With a diagnosis, you could also describe this in your college applications. If your other grades are strong and it is obviously a specific problem, they will take that into account when looking at your application.

How peculiar! Everybody has their strengths and weaknesses. As for me, on the SAT reasoning test I made an 800 in math, 580 in criticial reading, and 540 in writing. Similar to your isolated skill in English, my math in contrast to everthing else I do is freakishly good. I suggest taking an official IQ test where you can see an in-depth score report. It'll tell you what you're strengths and weaknesses are. Getting an A in calculus is something to be proud of; you're right in saying that it's more geometric than numeric, so perhaps you have a heightened sense of visualization which might relate to English.
You should never leave things blank on the SAT. Every wrong answer deducts 1/4 of it's worth. Statistically speaking, you have a 100% chance to get one in every 4 right. This would mean for every 4 questions, you get 1 right and 3 wrong. This gives you 1 point up, and deducts 3/4 because of 3 wrong answers. In the end, you're 1/4 point up!

Math Question? Please help! 8th Grade?

We Answered:

You write out the components, and perform the operations in operator order. Do the powers first, then the multiplications, then the addition.
20 * 10^5 + 4 * 10^6

Of course, there's something interesting you may have noticed right off the bat. 20*10^5 is equal to 2*10^6.

So you have
2*10^6 + 4*10^6
= 6*10^6
= 6,000,000
