Arithmetic

Arithmetic is both the easiest math to master and the branch of math most used, as people very often need to know "How many of (something) is here?" even if they are not a scientist nor an engineer or something like that. As said in the introduction (which you should have read before this), arithmetic goes over only numbers and their operations, plus, minus, multiply, divide, power, and logarithms. Arithmetic is the most important part of math, as it builds the foundation for all the other branches and is used the most at every level. Learning arithmetic starts most commonly at Pre-school, the earliest of education. There, most people will continue to strengthen their understanding until the end of their first or second year of primary school. When most students are in second-year or third-year primary school, they will learn multiplication and division, perhaps memorizing basic multiplication tables, and learn about decimals, percents, fractions, which are just another to express division, and negative numbers. After that, most students will learn about exponents and square roots, as well as advanced things like prime factorization and non-integer operations. Lastly, logarithms, the most complicated operation, is usually learned in early algebra. This is a map of arithmetic in US learning, and these concepts will all be explained in the subpages.
