Most Americans forget the basic subjects like English, math, geography, history and science, that they learn at elementary school when they’re in the fifth grade. These subjects are incredibly important to the functioning of everyday human beings, although they don’t seem like it. That’s why it’s super important to make sure that you don’t forget the basics, even as you head into adulthood. Important basics to know include how to form a sentence using the correct grammar and spelling, basic mathematics skills that incorporate basic geometry, fractions and prime numbers, basic science knowledge, including planets and animals, and also key historical dates that are crucial to the world we know today. So how many questions can you correctly answer about grammar, punctuation and spelling, the way you would have to in an English class? How many questions can you get right about basic mathematics, including fractions, geometry, angles, prime numbers and simple multiplication?
